Rob Crittenden 65d38af9e2 Skip lock and fork in ipa-server-guard on unsupported ops
On startup certmonger performs a number of options on the
configured CA (IPA, not to be confused with the real dogtag CA)
and the tracking requests.

Break early for operations that are not supported by ipa-submit.
This will save both a fork and a lock call.
