a81310e23d rest api: add a new /system/log operation
Add a new REST API operation, taking a log level and a message, and
printing it into the Scylla log.

This can be useful when a test wants to mark certain positions in the
log (e.g., to see which other log messages we get between the two
positions). An alternative way to achieve this could have been for the
test to write directly into the log file - but an on-disk log file is
only one of the logging options that Scylla support, and the approach
in this patch allows to add log message regardless of how Scylla keeps
the logs.

In motivation of this feature is that in the following patch the
test/alternator framework will add log messages when starting and
ending tests, which can help debug test failures.

fcb8d040e8 treewide: use Software Package Data Exchange (SPDX) license identifiers
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

bbad8f4677 replica: move ::database, ::keyspace, and ::table to replica namespace
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.

ae3a360725 database: Move database, keyspace, table classes to replica/ directory
The database, keyspace, and table classes represent the replica-only
part of the objects after which they are named. Reading from a table
doesn't give you the full data, just the replica's view, and it is not
consistent since reconciliation is applied on the coordinator.

As a first step in acknowledging this, move the related files to
a replica/ subdirectory.

761f89e55e api: Introduce system/drop_sstable_caches RESTful API
Evicts objects from caches which reflect sstable content, like the row
cache. In the future, it will also drop the page cache
and sstable index caches.

Unlike lsa/compact, doesn't cause reactor stalls.

The old lsa/compact call invokes memory reclamation, which is
non-preemptible. It also compacts LSA segments, so does more
work. Some use cases don't need to compact LSA segments, just want the
row cache to be wiped.

88ade3110f treewide: replace calls to engine().some_api() with some_api()
This removes the need to include reactor.hh, a source of compile
time bloat.

In some places, the call is qualified with seastar:: in order
to resolve ambiguities with a local name.

Includes are adjusted to make everything compile. We end up
having 14 translation units including reactor.hh, primarily for
deprecated things like reactor::at_exit().
