gear and systemd react badly to long names starting with _

Disable the docker image cleanup step which was failing intermittently and test that links also work with other local addresses.
Start of including IP address as part of PortMap

Continuation of adding internal_address to PortMap
Account for PortMap changes

Attempt to connect in a loop which allows us to remove all the sleeps
use twisted to capture the lines sent from the container
remove some of the changes associated with the earlier PortMap.external_address experiment.
