The `keyspace_compaction` method incorrectly appends the column family
parameter to the URL using a regular string, `"?cf={table}"`, instead of
an f-string, `f"?cf={table}"`. As a result, the column family name is
sent as `{table}` to the server, causing the compaction request to fail.
Fix this issue by passing the parameter to the POST request using a
dictionary instead of appending it to the URL.

before this change, we use the default options when creating `test_env`,
and the default options enable `use_uuid`. but the modes of
`perf-sstables` involving reads assumes that the identifiers are
deterministic. so that the previously written sstables using the "write"
mode can be read with the modes like "index_read", which just uses
`test_env::make_sstable()` in `load_sstables()`, and under the hood,
`test_env::make_sstable()` uses `test_env::new_generation()` for
retrieving the next identifier of sstable. when using integer-base
identifier, this works. as the sstable identifiers are generated
from a monotonically increasing integer sequence, where the identifiers
are deterministic. but this does not apply anymore when the UUID-based
identifiers are used, as the identifiers are generated with a
pseudorandom generator of UUID v1.
in this change, to avoid relying on the determinism of the integer-based
sstable identifier generation, we enumerate sstables by listing the
given directory, and parse the path for their identifier.
after this change, we are able to support the UUID-based sstable
identifier.
another option is disable the UUID-based sstable identifier when
loading sstables. the upside is that this approach is minimal and
straightforward. but the downside is that it encodes the assumption
in the algorithm implicitly, and could be confusing -- we create
a new generation for loading an existing sstable with this generation.

Now the endpoint hanler gets the value from db::config which is not nice
from several perspectives. First, it gets config (ab)using database.
Second, it's compaction manager that "knows" its throughput, global
config is the initial source of that information.

Currently the major compaction task impl grabs this (non-updateable)
value from db::config. That's not good, all services including
compaction manager have their own configs from which they take options.
Said that, this patch puts the said option onto
compaction_manager::config, makes use of it and configures one from
db::config on start (and tests).

in 947e2814, we pass `--tty` as long as we are using podman _or_
we are in interactive mode. but if we build the tree using podman
using jenkins, we are seeing that ninja is displaying the output
as if it's in an interactive mode. and the output includes ASCII
escape codes. this is distracting.
the reason is that we
* are using podman, and
* ninja tells if it should displaying with a "smart" terminal by
checking istty() and the "TERM" environmental variable.
so, in this change, we add --tty only if
* we are in the interactive mode.
* or stdin is associated with a terminal. this is the use case
where user uses dbuild to interactively build scylla

in 30e82a81, we add a contraint to the template parameter of
boost_test_print_type() to prevent it from being matched with
types which can be formatted with operator<<. but it failed to
work. we still have test failure reports like:
```
[Exception] - critical check ['s', 's', 't', '_', 'm', 'r', '.', 'i', 's', '_', 'e', 'n', 'd', '_', 'o', 'f', '_', 's', 't', 'r', 'e', 'a', 'm', '(', ')'] has failed
```
this is not what we expect. the reason is that we passed the template
parameters to the `has_left_shift` trait in the wrong order, see
https://live.boost.org/doc/libs/1_83_0/libs/type_traits/doc/html/boost_typetraits/reference/has_left_shift.html.
we should have passed the lhs of operator<< expression as first
parameter, and rhs the second.
so, in this change, we correct the type constraint by passing the
template parameter in the right order, now the error message looks
better, like:
```
test/boost/mutation_query_test.cc(110): error: in "test_partition_query_is_full": check !partition_slice_builder(*s) .with_range({}) .build() .is_full() has failed
```
it turns out boost::transformed_range<> is formattable with operator<<,
as it fulfills the constraints of `boost::has_left_shift<ostream, R>`,
but when printing it, the compiler fails when it tries to insert the
elements in the range to the output stream.
so, in order to workaround this issue, we add a specialization for
`boost::transformed_range<F, R`.
also, to improve the readability, we reimplement the `has_left_shift<>`
as a concept, so that it's obvious that we need to put both the output
stream as the first parameter.

Now, when each shard storage_group_manager keeps
only the storage_groups for the tablet replica it owns,
we can simple return the storage_group map size
instead of counting the number of tablet replicas
mapped to this shard.
Add a unit test that sums the tablet count
on all shards and tests that the sum is equal
to the configured default `initial_tablets.

…utations vector
With a large number of table the schema mutations
vector might get big enoug to cause reactor stalls when freed.
For example, the following stall was hit on
2023.1.0~rc1-20230208.fe3cc281ec73 with 5000 tables:
```
(inlined by) ~vector at /usr/bin/../lib/gcc/x86_64-redhat-linux/12/../../../../include/c++/12/bits/stl_vector.h:730
(inlined by) db::schema_tables::calculate_schema_digest(seastar::sharded<service::storage_proxy>&, enum_set<super_enum<db::schema_feature, (db::schema_feature)0, (db::schema_feature)1, (db::schema_feature)2, (db::schema_feature)3, (db::schema_feature)4, (db::schema_feature)5, (db::schema_feature)6, (db::schema_feature)7> >, seastar::noncopyable_function<bool (std::basic_string_view<char, std::char_traits<char> >)>) at ./db/schema_tables.cc:799
```
This change returns a mutations generator from
the `map` lambda coroutine so we can process them
one at a time, destroy the mutations one at a time, and by that, reducing memory footprint and preventing reactor stalls.

Currently, database::tables_metadata::add_table needs to hold a write
lock before adding a table. So, if we update other classes keeping
track of tables before calling add_table, and the method yields,
table's metadata will be inconsistent.
Set all table-related info in tables_metadata::add_table_helper (called
by add_table) so that the operation is atomic.
Analogically for remove_table.

It is unsafe to restrict the sync nodes for repair to the source data center if it has too low replication factor in network_topology_replication_strategy, or if other nodes in that DC are ignored.
Also, this change restricts the usage of source_dc to `network_topology` and `everywhere_topology`
strategies, as with simple replication strategy
there is no guarantee that there would be any
more replicas in that data center.

Replace raft_server_snapshot_reduce_threshold with raft_server_set_snapshot_thresholds in tests
as raft_server_set_snapshot_thresholds fully covers the functionality of raft_server_snapshot_reduce_threshold.
before this change, `scylla sstable shard-of` didn't support tablets,
because:
- with tablets enabled, data distribution uses the scheduler
- this replaces the previous method of mapping based on vnodes and shard numbers
- as a result, we can no longer deduce sstable mapping from token ranges
in this change, we:
- read `system.tablets` table to retrieve tablet information
- print the tablet's replica set (list of <host, shard> pairs)
- this helps users determine where a given sstable is hosted
This approach provides the closest equivalent functionality of
`shard-of` in the tablet era.
