Backport

This PR is auto-generated from #3284 to be assessed for backporting due to the inclusion of the label backport/1.3.x.

The below text is copied from the body of the original PR.


Changes proposed in this PR:

When setup as a secondary in WAN federation, Consul migrates config entries from the primary datacenter into the kubernetes secondaries. When the config entries are saved, the partition field in the spec of the config entries that have them, gets normalized to the value default if it was previously "" in Consul Enterprise. CRDs for these resources then constantly re-sync themselves since the MatchesConsul method, which is responsible for identifying diffs, evaluates the match incorrectly.

To normalize this behavior, the comparison operation for the impacted CRDs has been updated so that when the Partition fields are compared, empty strings are normalized to the value default. This should ensure that those two values are considered symmetrical and hence should prevent the constant resync of the CRDs into Consul.

How I've tested this PR:

  • Unit tests.
  • Tested on env where this behavior was previously observed and has now stopped occurring.

How I expect reviewers to test this PR:

  • Kind eyes and a whimsical smile. Also, suggestions for additional test cases if you come across them.
