Add API test for resizing a stopped server

The compute API allows resizing a stopped server but we don't test it
and we've regressed that flow in the past, so add a test to guard
against it.

Revert "Fail fast during advanced networking test"

This reverts commit ae3dbdc11fc182109ca07253b0d81183321d7f1c.

Commit ae3dbdc11fc182109ca07253b0d81183321d7f1c was seen as the recent spike for
the "ssh timeout" failures in neutron, as referenced by this bug [1]. With this
revert, we hope to get things moving again while we root cause the other issue.
We will re-submit ae3dbdc11fc182109ca07253b0d81183321d7f1c to continue
debugging as well.
