Previously, any attempt to take a materialized view or secondary index
snapshot was considered a mistake and caused the snapshot operation to
abort, with a suggestion to snapshot the base table instead.
But an automatic pre-scrub snapshot of a view cannot be attributed to
user error, so the operation should not be aborted in that case.
(It is an open question whether the more correct thing to do during
pre-scrub snapshot would be to silently ignore views. Or perhaps they
should be ignored in all cases except when the user explicitly asks to
snapshot them, by name)
Closes#10760.

Fixes#10760.
This series refactors `table::snapshot` and moves the responsibility
to flush the table before taking the snapshot to the caller.
`flush_on_all` and `snapshot_on_all` helpers are added to replica::database
(by making it a peering_sharded_service) and upper layers,
including api and snapshot-ctl now call it instead of calling cf.snapshot directly.
With that, error are handed in table::snapshot and propagated
back to the callers.
Failure to allocate the `snapshot_manager` object is fatal,
similar to failure to allocate a continuation, since we can't
coordinate across the shards without it.
Test: unit(dev), rest_api(debug)

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
test/rest_api has a "--ssl" option to use encrypted CQL. It's not clear
to me why this is useful (it doesn't actually test encryption of the
REST API!), but as long as we have such an option, it should work.
And it didn't work because of a typo - we set a "check_cql" variable to the
right function, but then forgot to use it and used run.check_cql instead
(which is just for unencrypted cql).

Splits and validate the cf parameter, containing an optional
comma-separated list of table names.
If any table is not found and a no_such_column_family
exception is thrown, wrap it in a `bad_param_exception`
so it will translate to `reply::status_type::bad_request`
rather than `reply::status_type::internal_server_error`.
With that, hide the split_cf function from api/api.hh
since it was used only from api/storage_service
and new use sites should use validate_tables instead.
