test_rebuild_volume_backed_server failing 100% on nova-lvm job

After the tempest patch was merged [1] nova-lvm job started to fail with the following error in test_rebuild_volume_backed_server:

Traceback (most recent call last):
  File "/opt/stack/tempest/tempest/common/utils/__init__.py", line 70, in wrapper
    return f(*func_args, **func_kwargs)

    raise lib_exc.InvalidParam(invalid_param=msg)
tempest.lib.exceptions.InvalidParam: Invalid Parameter passed: When validation.connect_method equals floating, validation_resources cannot be None

As discussed on IRC with Sean [2], the SSH validation is mandatory now which is disabled in the job config [2].
