Description of problem: During performance testing, when stress testing the rbac ui using multicluster-role-assignment, the cluster permission yaml eventually gets cutoff at around 5000 - 6000 lines in the yaml

Version-Release number of selected component (if applicable): ACM 2.15

How reproducible: Always

Steps to Reproduce:

1. Apply a large enough MRA with enough data so that the clusterpermission yaml contains enough data to display 5000+ lines of data

Actual results: clusterpermission yaml gets cutoff at around 5000 lines of yaml

Solution - Fix the multicluster-role-assignment controller so that multiple clusterpermissions gets created instead of just one per cluster
