Implement some kind of centralised logging

It would be nice to have a kibana dashboard or similar for capturing and searching the logs from the Python logging module. Unfortunately the centralised CERN monit service can't be used as the data is isn't "public" (at the very least it contains personally identifiable information).

Currently this information is only kept in OpenShift for a short time period and it's kind of a pain to search.

Hopefully a common openshift template can be found for both Analysis Production's logs and the lbtaskrun logs.
