Avoid use of 'service --status-all' which is currently
broken on trusty for upstart managed daemons; the change
moves to detecting how the daemon is managed, and then
using upstart status XXX or the return code of service XXX
status to determine whether a process is running.
Fixes for IPv6 network address detection under Ubuntu
16.04 which changes the output format of the ip commands
slightly.
Update the version map to include 8.1.x as a Neutron
version for Mitaka.
