test_attach_detach_volume not running in the gate

[Andrea Frittoli]

The following tests:

test_attach_detach_volume[id-52e9045a-e90d-4c0d-9087-79d657faffff]
test_attach_volume_shelved_or_offload_server[id-13a940b6-3474-4c3c-b03f-29b89112bfee]

are not executed in the gate, they are skipped because run_validation is turned off.
The only run on the non-voting neutron-ssh job.

While we aim to turn validation into a voting job, we should run these tests now.
The skip part should be specific to the validation bit, and not to the entire test.

This caused https://bugs.launchpad.net/tempest/+bug/1600186 to slip through the gate.

    Run attach/detach volume tests even without ssh

    When validation it's turned off, it is still possible to run the
    attach/detach volume tests. They will test less, but still be
    valuable.

    Tests modified:
    - test_attach_detach_volume
    - test_attach_volume_shelved_or_offload_server
    - test_detach_volume_shelved_or_offload_server

    Not having them running in the gate allowed for bug/1600186 to
    slipt through.
