Add last synced time to CRDs

[thisisnotashwin]

Changes proposed in this PR:

• Update CRDs to have printer column for "Last Synced At" which displays time since the last successful sync of a resource with the Consul Server.
  Companion PR to Add LastSyncedTime field on CRDs consul-k8s#448
  How I've tested this PR:
• Deployed consul-helm with the image: ashwinvenkatesh/consul-k8s@sha256:8f2d59278f4b8deca8eaeb643a3e6143684e4c37a3e03c051781a1c42a8d70d4 for consul-k8s
• Created a resource and kubectl get resource now displays a column Last Synced At with time since the successful sync.

How I expect reviewers to test this PR:

• Retry the above step. Potentially edit the object to observe the Last Sync time update itself.
  Edit the config with a "failing" spec and save it. The Last Synced time should now not update as the sync will be unsuccessful.

Checklist:

• Bats tests added
• CHANGELOG entry added (HashiCorp engineers only, community PRs should not add a changelog entry)

Looks great!
Curious if the two descriptions should be the same text and also should both descs end with a period? If not it looks 💯

@kschoche I looked at what we have done previously and it seems consistent with the way that we have setup other printer columns and also descriptions for fields.

LGTM. Just verifying you use the make ctrl-crd-copy helm=<path-to-consul-helm-repo> command?

@lkysow I did and it was glorious!
