Implement a new command ipa-clrgen-manage to enable, disable, or check the status of CRL generation on the localhost. The command automates the manual steps described in the wiki https://www.freeipa.org/page/Howto/Promote_CA_to_Renewal_and_CRL_Master Fixes: https://pagure.io/freeipa/issue/5803 Reviewed-By: Rob Crittenden <rcritten@redhat.com> Reviewed-By: Francois Cami <fcami@redhat.com>
