Add Support for Mounting a Persistent Volume Claim

As far as I know the only way to mount a persistent volume claim in a deployed container is to override the default chart. It would be nice if there was a way to mount a PVC to a folder within a container using the default deploy chart.

I will be submitting an MR with a possible approach to providing this functionality.

Release notes

We have added the ability to mount a Persistent Volume Claim in a container.
