Container service updates (#141)

Adds automatic pulling/updating of container service images as part of
ansible run.
This is useful in helping to keep the container service up to date with
the latest images.

I have also added a REST call to enable the AutoRun pipeline if a flag
is set. The AutoRun pipeline is currently needed to send session archive
notification emails, but can be disabled (default) if these are not
required.
