We merged change I9459e47ecfd19b27b7adcaee9ce91f80d51c124d which
should have opened this port but did not. Add testing for it.
Remove eavesdrop from webservers group
This was overridding the custom iptables ports that were being set
in the eavesdrop group vars file. There appears to be no other use
for the webservers group.
