MaterializedViewMetadataTestComplex.test_metadata_with_quoted_identifiers is failing across the board

[fruch]

MaterializedViewMetadataTestComplex.test_metadata_with_quoted_identifiers started failing with:

cassandra.InvalidRequest: Error from server: code=2200 [Invalid query] message="The IS NOT NULL restriction is allowed only columns which are part of the view's primary key, found columns: the Value. The flag strict_is_not_null_in_views can be used to turn this error into a warning, or to silence it. (true - error, warn - warning, false - silent)"

it's cause of a recent change in scylla master

there are few options to handle:

1. skip this test across all versions
2. patch all versions to pass strict_is_not_null_in_views: warn to scylla yaml for this test

I think 2 is better, since we'll need to fix this also on pyton-driver itself.
