Set keystone admin_bind_host to KEYSTONE_SERVICE_HOST

Browse Source 
On Linux ports 32768-61000 can be used by just about
anything needing a socket. Keystone's IANA assigned port is 35357.
Occasionally something else will be using port 35357 first because Linux
allows this. Workaround is to bind to port 127.0.0.1 instead of 0.0.0.0.
$KEYSTONE_SERVICE_HOST gets its value from $SERVICE_HOST which is set to
127.0.0.1 in the gate.

"Ephemeral (client) ports will *never* be sourced from 0.0.0.0, and are
uniquely identified by the full connection five-tuple (proto, src IP,
src port, dst IP, dst port) anyway, allowing them to overlap src IP/src
port as long as proto/dst IP/dst port are different. Thus it is up to
keystone/devstack to bind more appropriately and not use wildcard bind
addresses unless explicitly necessary for some reason. For example, in
the log output, the URLs are configured with dst IPs of 127.0.0.1
anyway, so binding explicitly to localhost would change nothing, while
skirting this particular edge case nicely." ~Evan Callicoat

This doesn't fix bug 1253482 it works around it while a better solution
is prepared (running keystone behind apache in devstack).
