Test attached volume extend actions in the nova-next job
Test attached volume extend actions in the nova-next job

Currently we don't have test coverage for volume extend of attached
volumes and we recently had a bug around extending attached LUKSv2
encrypted volumes.

This adjusts the test regex to include volume extend tests and enables
the corresponding features in the volume service so the tests will run.
