What type of PR is this?
/kind feature
/kind api-change

What this PR does / why we need it:
This adds a conditions field to the PDB status object and updates the disruption controller to use the DisruptionAllowed condition. This provides information that to some extent is already available through the status.DisruptionsAllowed field, but with this condition we can also communicate the reason why the value of status.DisruptionsAllowed are set to 0. This can be either because not enough pods are available, or because the disruption controller experienced an error.

This addresses one of the issues described in the PDB to GA KEP: kubernetes/enhancements#2114

Which issue(s) this PR fixes:

Special notes for your reviewer:

Does this PR introduce a user-facing change?:

PodDisruptionBudget API objects can now contain conditions in status.

Additional documentation e.g., KEPs (Kubernetes Enhancement Proposals), usage docs, etc.:

EvictionREST#checkAndDecrement updates PDB status... should it set this condition as well?

addressing this in a separate PR sounds good to me. I don't think this change makes the issue worse, and gives us a potential tool to address the issue in a follow up
