Comment 7 for bug 1922784

TBH, tripleo jobs are running a basic manila integration test that doesn't test snapshots at all; so the tempest plugin could ignore the "snapshot_support" and "create_share_from_snapshot_support" optional capabilities too.

We're working along those lines and limiting the use of these optional directives in the tests: https://review.opendev.org/c/openstack/manila-tempest-plugin/+/785307

This will take some time and testing on our end because these have been around for a long time. In the meanwhile, allowing auto configuration via tempestconf is a decent solution that should work across releases - and that would prevent us from needing to investigate a way to set test configuration per release.
