templates/openshift: grab bootstrap log on failure

This uses the Terraform state to discover the IP address of the
bootstrap node (ideally, the installer will provide this information in
a form which easier to consume in the future). It then connects to the
gatewayd instance on that machine and pulls the logs for various
services. Hopefully, these logs will be useful when diagnosing
installation failures.
