Fix renewal lock issues on installation

- Make sure that the file /var/run/ipa/renewal.lock is deleted upon
uninstallation, in order to avoid subsequent installation issues.

- Modify certmonger renewal script: restart the http/dirsrv services
only if they were already running

- Cleanup certmonger ra renewal script: no need to restart httpd

- Reorder during http install: request the SSL cert before adding
ipa-service-guard
Rationale: when a CA helper is modified, certmonger launches the helper
with various operations (FETCH_ROOTS, ...) If the CA helper is once again
modified, the on-going helper is killed. This can lead to
ipa-service-guard being killed and not releasing the renew lock.

If the SSL cert is requested with IPA helper before ipa-service-guard is added,
we avoid this locking issue.

Part of the refactoring effort, certificates sub-effort.
