This change adds a member function that can be used
to access 'storage_service/ownership' API.
It will be used by tests that need to access this API.

This change is intended to introduce tests for vnodes for
the following API paths:
- 'storage_service/ownership'
- 'storage_service/ownership/{keyspace}'
In next patches the logic that is tested will be adjusted
to work correctly when tablets are enabled. This is a safety
net that ensures that the logic is not broken.

The test cases in this suite need to start scylla with custom config options, restart it and call API on it. By the time the suite was created all this wasn't possible with any library facility, so the suite carries its version of managed_cluster class that piggy-backs cql-pytest scylla starting. Now test.py has pretty flexible manager that provides all the scylla cluster management object_store suite needs.

Today's test.py allows filtering tests to run with the `test.py --options name` syntax. The "name" argument is then considered to be some prefix, and when iterating tests only those whose name starts with that prefix are collected and executed. This has two troubles.
Minor: since it is prefix filtering, running e.g. topology_custom/test_tablets will run test_tablets _and_ test_tablets_migration from it. There's no way to exclude the latter from this selection. It's not common, but careful file names selection is welcome for better ~~user~~ testing experience.
Major: most of test files in topology and python suites contain many cases, some are extremely long. When the intent is to run a single, potentially fast, test case one needs to either wait or patch the test .py file by hand to somehow exclude unwanted test cases.
This PR adds the ability to run individual test case with test.py. The new syntax is `test.py --options name::case`. If the "::case" part is present two changes apply.
First, the test file selection is done by name match, not by prefix match. So running topology_custom/test_tablets will _not_ select test_tablets_migration from it.
Second, the "::case" part is appended to the pytest execution so that it collects and runs only the specified test case.

The test is booting nodes, and then immediately starts shutting down
nodes and removing them from the cluster. The shutting down and
removing may happen before driver manages to connect to all nodes in the
cluster. In particular, the driver didn't yet connect to the last
bootstrapped node. Or it can even happen that the driver has connected,
but the control connection is established to the first node, and the
driver fetched topology from the first node when the first node didn't
yet consider the last node to be normal. So the driver decides to close
connection to the last node like this:
```
22:34:03.159 DEBUG> [control connection] Removing host not found in
peers metadata: <Host: 127.42.90.14:9042 datacenter1>
```
Eventually, at the end of the test, only the last node remains, all
other nodes have been removed or stopped. But the driver does not have a
connection to that last node.
Fix this problem by ensuring that:
- all nodes see each other as NORMAL,
- the driver has connected to all nodes
at the beginning of the test, before we start shutting down and removing
nodes.

It might happen that multiple tablets co-habit the same shard, so we want load-and-stream to jump into a new streaming session for every tablet, such that the receiver will have the data properly segregated. That's a similar treatment we gave to repair. Today, load-and-stream fails due to sstables spanning more than 1 tablet in the receiver.
Synchronization with migration is done by taking replication map, so migrations cannot advance while streaming new data. A bug was fixed too, where data must be streamed to pending replicas too, to handle case where migration is ongoing and new data must reach both old and new replica set. A test was added stressing this synchronization path.
Another bug was fixed in sstable loading, which expected sharder to not be invalidated throughout the operation, but that breaks during migrations.
Fixes#17315.

Where an update sometimes failed due to an internal server error, and the
log had the mysterious warning message:
"std::logic_error (Empty materialized view updated)"
We've also seen this log-message in the past in another user's log, and
never understood what it meant.
It turns out that the error message was generated (and warning printed)
while building view updates for a base-table mutation, and noticing that
the base mutation contains an *empty* row - a row with no cells or
tombstone or anything whatsoever. This case was deemed (8 years ago,
in d5a61a8c48) unexpected and nonsensical,
and we threw an exception. But this case actually *can* happen - here is
how it happened in test_table_alter_delete - which is a test involving
a strange combination of materialized views, LWT and schema changes:
1. A table has a materialized view, and also a regular column "int_col".
2. A background thread repeatedly drops and re-creates this column
int_col.
3. Another thread deletes rows with LWT ("IF EXISTS").
4. These LWT operations each reads the existing row, and because of
repeated drop-and-recreate of the "int_col" column, sometimes this
read notices that one node has a value for int_col and the other
doesn't, and creates a read-repair mutation setting int_col (the
difference between the two reads includes just in this column).
5. The node missing "int_col" receives this mutation which sets only
int_col. It upgrade()s this mutation to its most recent schema,
which doesn't have int_col, so it removes this column from the
mutation row - and is left with a completely empty mutation row.
This completely empty row is not useful, but upgrade() doesn't
remove it.
6. The view-update generation code sees this empty base-mutation row
and fails it with this std::logic_error.
7. The node which sent the read-repair mutation sees that the read
repair failed, so it fails the read and therefore fails the LWT
delete operation.
It is this LWT operation which failed in the test, and caused
the whole test to fail.
The fix is trivial: an empty base-table row mutation should simply be
*ignored* when generating view updates - it shouldn't cause any error.
Before this patch, test_table_alter_delete used to fail in roughly
20% of the runs on my laptop. After this patch, I ran it 100 times
without a single failure.

There are 4 barrier-only stages when migrating a tablet and the test needs to fail pending/leaving replica that handles it in order to validate how coordinator handles dead node. Failing the barrier is done by suspending it with injection code and stopping the node without waking it up. The main difficulty here is how to tell one barrier RPC call from another, because they don't have anything onboard that could tell which stage the barrier is run for. This PR suggests that barrier injection code looks directly into the system.tablets table for the transition stage, the stage is already there by the time barrier is about to ack itself over RPC.

The author (me) tried to be clever and fix the formatting, but then he
realized this just means a lot of unnecessary fighting with tests. So
this patch makes the formatting compatible with that of the legacy
nodetool:
* Use compatible rounding and precision formatting
* Use incorrect unit (KB instead of KiB)
* Align numbers to the left
* Add trailing white-space to "Snapshot Details: "
These two parameters are not used by the native nodetool, because
ScyllaDB itself doesn't support them. These should be just ignored and
indeed there was a unit test checking that this is the case. However,
due to a mistake in the unit test, this was not actually tested and
nodetool complained when seeing these params.
This patch fixes both the test and the native nodetool.

instead of using the hand-crafted operator==, use the default-generated
one, which is equivalent to the former.
regarding the difference between global operator== and member operator==,
the default-generated operator in C++20 is now symmetric. so we don't
need to worry about the problem of `max_result_size` being lhs or rhs.
but neither do we need to worry about the implicit conversion, because
all constructors of `max_result_size` are marked explicit. so we don't
gain any advantage by making the operator== global instead of a member
operator.
