turn off clean log checking

The effort to clean out the issues in the logs in OpenStack has
largely stalled, and the impact of this is currently just a lot more
spurious failures that aren't getting looked at. Also it's kind of a
layer violation given that the checker is in Tempest but called from
devstack-gate.

The number of logs that were actually considered clean is actually
very small (only 4 or 5 out of 30), so this wasn't really preventing
many new bugs from entering. Removing it will decrease failure rates
for tempest runs which otherwise passed.

Don't use ephemeral volumes for Ironic agent driver

The agent driver (unfortunately) does not support ephemeral volumes
yet. This change sets ephemeral volume size to 0, which is checked
by Tempest when testing ephemeral support.
