Use dogtag-ipa-ca-renew-agent to track certificates on master CA.
Before, dogtag-ipa-renew-agent was used to track the certificates and the certificates were stored to LDAP in renew_ca_cert and renew_ra_cert. Since dogtag-ipa-ca-renew-agent can store the certificates itself, the storage code was removed from renew_ca_cert and renew_ra_cert. Reviewed-By: Petr Viktorin <pviktori@redhat.com>
