Made Test Volume Names Time-Unique To Avoid Test Problems

When the test creates volumes, the volumes are now named
after the time they were created at. This is to avoid
attempts to create two volumes with the same name by
two simultaneous Jenkins jobs. This patch is based on
a  previous patch but now depends on tox.
