Extend service timeout
Extend service timeout

Glance seems to be having issues getting started in time.

At least a couple times recently devstack exited because glance
was not running with-in 60 seconds. Logs in one case seemed to
lean to well over a minute, as such lets extend the timeout
and see if that stabilizes CI further.
