bring over pretty_tox.sh from tempest
Tempest developed a set of wrappers around testr to print out tests as they are running through using the subunit stream. This also displays which workers the various tests are running on. Adapted for nova's need for loading the locking. I expect that the needs of nova will diverge this over time, especially what's displayed during tracing, as such I think it's fine to just do a transplant and not try to turn this into some external repo.
