Is your feature request related to a problem? Please describe.
Our monitoring configuration identifies different workloads using Pod labels. Currently there is no way to configure custom Pod labels in the CR.

Describe the solution you'd like
Custom Pod label configuration for any of the Pulpcore Types.

Describe alternatives you've considered
There are solutions we could implement that couple to the existing default labels the operator adds
to Pods, but I would prefer not to rely on these labels remaining static.
