Tempest runs volume snapshot tests even when volume snapshots are disabled

[Matt Riedemann]

I noticed this in this change:

https://review.openstack.org/#/c/395887/

meant to get the NFS job working.

These tests aren't checking if CONF.volume_feature_enabled.snapshot is False or not before running the tests:

    Add missing volume snapshot skip

    The following patch [1] that disables volume snapshots, fails with
    the error: "'NfsDriver' object has no attribute 'create_snapshot'".
    This patch adds the missing CONF.volume_feature_enabled.snapshot
    skip to that test.
