Add subunit-trace and ostestr
This commit migrates the current subunit trace commit from tempest-lib with the commits: d7c3f6b Merge "Summarize expected failures" e29ec71 Summarize expected failures 21e3f6a Enable stdout passthrough for subunit-trace d588748 Default the worker number to 0 not NaN 87c1442 Fix subunit-trace on python < 2.7 b73b9eb bring over fail only functionality from nova 5715fd6 Switch to elapsed time in subunit-trace summary d2e4040 Setup subunit-trace as an entry point and also adds the start of the ostestr command to wrap testr.
