Improve firewall checks

Chris St. Pierre authored 9 years ago

The firewall checks can fail for any number of reasons -- e.g., the
ceph cluster hostnames are unresolvable from the ansible host, or the
ports are filtered by some intermediate hop, etc. Make two changes to
make those checks better:

* Set pipefail when running the checks, so if nmap itself fails the
  command will be marked as 'failed'. Specifically, this fixes the
  case where the hostnames cannot be resolved.
* Add a new variable, check_firewall, which can be used to disable
  checks entirely. Specifically, this fixes the case where some
  intermediate firewall filters the ports, so nmap returns "filtered".
