Fix stacking in queens, cleanup TEP-IP cfg

Tinyrpc version 0.7 was removed from python repo
when 0.8 was released, and in devstack, lastest version
available is 0.6. Not sure why devstack doesn't see
version 0.8 as being available (like I can on my local
setup, something in python env, maybe python version?),
but anyway, installing 0.6 gets queens to stacking again.

Cleanup TEP-IP config that I added earlier for genius autotz.
Changed genius code to use local_ip instead of TEP-IP in genius,
so no longer need this config.
