Conflicts:

the built-in pyrax.utils.wait_until method.

Fixes #4076

Merge branch 'service-enable-fix' of https://github.com/gottwald/ansible into gottwald-service-enable-fix

When service module is used on unsupported Linux system where init
script is used directly, LinuxService.svc_cmd is None so .endswith()
fails.

This extends fix from e2f20db5 also
for state=restarted.

Fixes issue #3533

Fixed missing required package in notes.

Also added this feature to the CHANGELOG

This patch also checks specifically for a return code of 255, which
indicates an unknown SSH error of some kind. When that happens, ansible
will now recommend running with -vvvv (if not enabled) or show the
output from 'ssh -vvv' (when it is enabled)
