The snitch/name endpoint needs snitch instance to get the name from.
Also the storage_service/reset_snitch endpoint will also need snitch
instance to call reset on.
This patch carries local snitch reference all thw way through API setup
and patches the get_name() call. The reset_snitch() will come in the
next patch

The implementation of a test api that helps testing task manager
api. It provides methods to simulate the operations that can happen
on modules and theirs task. Through the api user can: register
and unregister the test module and the tasks belonging to the module,
and finish the tasks with success or custom error.
The implementation of a task manager api layer. It provides
methods to list the modules registered in task_manager, list
tasks belonging to the given module, abort, wait for or retrieve
a status of the given task.
For cases where we have very high values set to permissions_cache validity and
update interval (E.g.: 1 day), whenever a change to permissions is made it's
necessary to update scylla config and decrease these values, since waiting for
all this time to pass wouldn't be viable.
This patch adds an API for resetting the authorization cache so that changing
the config won't be mandatory for these cases.
Usage:
$ curl -X POST http://localhost:10000/authorization_cache/reset

Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
Move replica-oriented classes to the replica namespace. The main
classes moved are ::database, ::keyspace, and ::table, but a few
ancillary classes are also moved. There are certainly classes that
should be moved but aren't (like distributed_loader) but we have
to start somewhere.
References are adjusted treewide. In many cases, it is obvious that
a call site should not access the replica (but the data_dictionary
instead), but that is left for separate work.
scylla-gdb.py is adjusted to look for both the new and old names.
Todays idea of API reg/unreg is to carry the target service via
lambda captures down to the route handlers and unregister those
handers before the target is about to stop.
This patch makes it so for the streaming API.

Pass down gossiper from main, converting it to a shard-local instance
in calls to register_api() (which is the point that broadcasts the
endpoint registration across shards).
This helps remove gossiper as a global variable.
Registration of the currently unused hinted handoff endpoints is moved
out from the set_server_done function. They are now explicitly
registered in main.cc by calling api::set_hinted_handoff and also
uninitialized by calling api::unset_hinted_handoff.
Setting/unsetting HTTP API separately will allow to pass a reference to
the sync_point_service without polluting the set_server_done function.
Both set_server_storage_service and set_server_storage_proxy set up
API handlers that need storage service to work. Now they all call for
global storage service instance, but it's better if they receive one
from main. This patch carries the sharded storage service reference
down to handlers setting function, next patch will make use of it.

Currntly API endpoints to start and stop cql_server and thrift
are registered right after the storage service is started, but
much earlier than those services are. In between these two
points a lot of other stuff gets initialized. This opens a small
window during which cql_server and thrift can be started by
hand too early.
The most obvious problem is -- the storage_service::join_cluster()
may not yet be called, the auth service is thus not started, but
starting cql/thrift needs auth.
Another problem is those endpoints are not unregistered on stop,
thus creating another way to start cql/thrif at wrong time.
Also the endpoints registration change helps further patching.

In storage_service's snapshot code there are checks for
_operation_mode being _not_ JOINING to proceed. The intention
is apparently to allow for snapshots only after the cluster
join. However, here's how the start-up code looks like
- _operation_mode = STARTING in storage_service::constructor
- snapshot API registered in api::set_server_storage_service
- _operation_mode = JOINING in storage_service::join_token_ring
So in between steps 2 and 3 snapshots can be taken.
Although there's a quick and simple fix for that (check for the
_operation_mode to be not STARTING either) I think it's better
to register the snapshot API later instead. This will help
greatly to de-bload the storage_service, in particular -- to
incapsulate the _operation_mode properly.
Note, though the check for _operation_mode is made only for
taking snapshot, I move all snapshot ops registration to the
later phase.

Implementation of nodetool toppartiotion query, which samples most frequest PKs in read/write
operation over a period of time.
Content:
- data_listener classes: mechanism that interfaces with mutation readers in database and table classes,
- toppartition_query and toppartition_data_listener classes to implement toppartition-specific query (this
interfaces with data_listeners and the REST api),
- REST api for toppartitions query.
Uses Top-k structure for handling stream summary statistics (based on implementation in C*, see #2811).
What's still missing:
- JMX interface to nodetool (interface customization may be required),
- Querying #rows and #bytes (currently, only #partitions is supported).
