In order to get similar behavior to the way testr out of the box
works, only displaying failing results, all the user to define
TRACE_FAILONLY environment variable (any value will do). After this
point only failures, and things leaking out of stderr will end up on
the screen.
We also need to remove the suppression of the inline fail dumps for
this to have the impact that you'd expect.

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.
