Allow installing keystoneauth from git

Keystoneauth is not marked as stable yet however to ensure that the
integration between it, keystoneclient and other services don't break
compatibility we want to test it with tempest.

Unfortunately you can't put -e links in requirements.txt files so add
it to devstack so we can set the test environment. This will also make
it available when keystoneauth is released.
