Wily: apache2 Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:70

[Ryan Beisner]

apache2 does not always start on Wily-Liberty. This does not appear to be a race in the charm, nor in the charm amulet test:

# syslog - openstack-dashboard/0

FYI - it may take a few test iterations to expose this, but it is frequent enough to block addition of Wily amulet test coverage for openstack-dashboard.

I believe this is caused by Bug #1552822 and a work around has already been committed to the charm
