Description of problem:

As mentioned in the conventions doc https://github.com/openshift/enhancements/blob/master/CONVENTIONS.md#high-availability, both user-workload prometheus and thanos ruler should have a replica count of 2 with hard affinities set till we bring descheduler into our product.

Version-Release number of selected component (if applicable):
4.8

How reproducible:
Always

Steps to Reproduce:
1. Enable user workload
2.
3.

Actual results:
prometheus-user-workload and thanos-ruler statefulsets use preferredDuringSchedulingIgnoredDuringExecution for node affinity.

Expected results:
they should use requiredDuringSchedulingIgnoredDuringExecution
