Michael Litvak b9ec1180f5 alternator: require rf_rack_valid_keyspaces when creating index ...

When creating an alternator table with tablets, if it has an index, LSI
or GSI, require the config option rf_rack_valid_keyspaces to be enabled.

The option is required for materialized views in tablets keyspaces to
function properly and avoid consistency issues that could happen due to
cross-rack migrations and pairing switches when RF-rack validity is not
enforced.

Currently the option is validated when creating a materialized view via
the CQL interface, but it's missing from the alternator interface. Since
alternator indexes are based on materialized views, the same check
should be added there as well.
