descheduler: Support labelSelector in RemoveDuplicates

Is your feature request related to a problem? Please describe.

Some strategies such as RemovePodsViolatingInterPodAntiAffinity support a labelSelector parameter. However, RemoveDuplicates does not support it and comes in handy in some scenarios.

Describe the solution you’d like

I’d like to support labelSelector to define a RemoveDuplicates strategy such as:

    strategies:
      RemoveDuplicates:
        enabled: true
        params:
          labelSelector:
            matchExpressions:
              - key: foo
                operator: NotIn
                values:
                  - bar

What version of descheduler are you using?

descheduler version: 0.20 but the same applies to 0.22 afaik

Additional context

Thank you!
