Handle exceptions from plugins gracefully

If a tempest plugin is poorly constructed and raises an exception
during register_opts this can interfere with the rest of tempest
running correctly. This commit makes the tempest plugin handling
a bit more defensive so things don't crash if a plugin raises an
exception, instead the error is logged and tempest moves on.
