install metrics in OpenShift

Description

Since we now have OpenShift with persistent storage, it's a good idea to set up logging [1] and metrics [2] to better see the state of our cluster

Metrics were deployed so closing this

After talking to OpenShift devs I got a suggestion on improving logging - we need replicas on logstash with host path persistent volumes and proper host to pod mappings to ensure proper data retention without actually using NFS. Need to review the docs on making that work and using centralized logging in general.

Strangely, the aggregated logs documentation suggests that centralized sotrage won't work so I deployed it with ephemeral storage.

For metrics, on Prod I used a persistent volume. One more issue is the certificate warning that appears due to the fact that metrics uses an internally issued certificate.

Done
