"Defines origin v3-format for system/schema tables, and use them for
schema storage/retrival.
Includes a legacy_schema_migrator implementation/port from origin. Note
that since we don't support features like triggers, functions and
aggregates, it will bail if encountering such a feature used.
Note also that this patch set does not convert the "hints" and
"backlog" tables, even though these have changed in v3 as well.
That will be a separate patch set.
Tested against dtests. Note that patches for dtest + ccm
will follow."
