purpose
Cql statements used to have two API functions, depends_on_keyspace and
depends_on_column_family. The former, took as a parameter only a table
name, which makes no sense. There could be multiple tables with the same
name each in a different keyspace and it doesn't make sense to
generalize the test - i.e to ask "Does a statement depend on any table
named XXX?"
In this change we unify the two calls to one - depends on that takes a
keyspace name and optionally also a table name, that way every logical
dependency tests that makes sense is supported by a single API call.
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
This is mostly a sed script that replaces methods' first argument
plus fixes of compiler-generated errors.

This patch adds support for new service level cql queries.
The queries implemented are:
CREATE SERVICE_LEVEL [IF NOT EXISTS] <service_level_name>
ALTER SERVICE_LEVEL <service_level_name> WITH param = <something>
DROP SERVICE_LEVEL [IF EXISTS] <service_level_name>
ATTACH SERVICE_LEVEL <service_level_name> TO <role_name>
DETACH SERVICE_LEVEL FROM <role_name>
LIST SERVICE_LEVEL <service_level_name>
LIST ALL SERVICE_LEVELS
LIST ATTACHED SERVICE_LEVEL OF <role_name>
LIST ALL ATTACHED SERVICE_LEVELS
