This series is part of the shared storage project.
The STORAGE option is designed to hold a map of options
used for customizing storage for given keyspace.
The option is kept in a system_schema.scylla_keyspaces table.
This option is guarded with a schema feature, because it's kept in a new schema table: `system_schema.scylla_keyspaces`.
Example of the contents of the new table:
```cql
cassandra@cqlsh> select * from system_schema.scylla_keyspaces;
keyspace_name | storage_options | storage_type
---------------+------------------------------------------------+--------------
ksx | {'bucket': '/tmp/xx', 'endpoint': 'localhost'} | S3
```
Native storage options are not kept in the table, as this format doesn't hold any extra options and it would therefore just be a waste of storage.
Closes #10144
