Bug 2058211

Tested with 3 OCP clusters, say hub, c1, and c2

Version:
OCP: 4.11.0-0.nightly-2022-07-29-173905
ODF: 4.11.0-129
CEPH: 16.2.7-112.el8cp (e18db2ff03ac60c64a18f3315c032b9d5a0a3b8f) pacific (stable)
ACM: 2.5.1

Updated with invalid format CIDRs as: 10.1.161@42/32, 10.1.161-43/32, 10.1.161.ab/32, and validation of CIDrs fails as expected. Based on observation moving bz to verified state.
