Replace all uses of virtual profiles with `dogtag-ipa-ca-renew-agent-reuse` and remove profile from the IPA CA certificate tracking request. This prevents virtual profiles from making their way into CSRs and in turn being rejected by certain CAs. This affected the IPA CA CSR with Microsoft CS in particular. https://pagure.io/freeipa/issue/5799 Reviewed-By: David Kupka <dkupka@redhat.com> Reviewed-By: Stanislav Laznicka <slaznick@redhat.com>
