Instead of making the change just for ansible-provision.sh make the
change for all ansible runs.  Most of them don't currently have this
problem right now but I think it makes sense to make them all consistent
and not have to worry about this problem in the future.

Updated ansible config to increase ControlPersist (fix timeouts on long running tasks for remote hosts)

support registration and login via apache + mod_wsgi + mod_shib

Note that we now thing that gunicorn and mod_wsgi should not live
on the same machine if they are running the exact same codebase
with the exact same edx logging directories.  This seems to
cause deadlock at random times
