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.

When ansible is going over a NAT Gateway or other intermdiate
network devices, the connection can time out if that device has
its own timeout setting for no traffic.  Setting the ServerAliveInterval
will ensure that there is data sent over the wire ever 30 seconds so the
connection does not get closed while running ansible tasks that take
over 5 minutes.

update packer scripts to use ansible bootstrap script

These defaults are conflicting with the overrides.
