Add GIT_TIMEOUT variable to watch git operations
During my CI testing of each devstack change I can often see git get
itself stuck and hang indefinitely. I'm not sure if it's transient
network issues, or issues at the remote end (seen with both github.com
and git.openstack.org) but it hits fairly frequently. Retrying the
command usually gets it going again. Searching for "git hanging" and
similar shows its not entirely uncommon...
This adds a watchdog timeout for remote git operations based on a new
environment variable GIT_TIMEOUT. It will retry 3 times before giving
up. The wrapper is applied to the main remote git calls.
