This was requested by consumers of the library so they don't have
to enable external locks globally with the OSLO_LOCK_PATH env var,
which can mask bugs in unit tests that have interdependencies
because it makes every lock in any unit test shared. The new
fixture allows a separate lock directory to be created for each
test, and allows external locking to only be enabled for tests
that need it.

Move the public API out of oslo.concurrency to oslo_concurrency. Retain
