K8SPSMDB-1561 Mount the DB PVC in the PMM3 container

[sfoulkes]

This is necessary to allow the node_exporter running in the pmm-client container to collect metrics on the database's persistent volume. This had been fixed for PMM2 in K8SPSMDB-1297 but that change didn't get picked up when PMM3 support was added to the operator shortly after.

We will have psmdb operator 1.22.0 release in two weeks.

For some reason, we had this fix prepared: #1927, but it was missed through the cracks somehow during the merging process.

Please have a look and update the unit tests accordingly.

Thanks!

[gkech]

created a jira ticket for this as well: K8SPSMDB-1561

[sfoulkes]

Thanks for the quick review @gkech and @hors. I've fixed the version and updated the unit test.
