This patch is for https://pagure.io/dogtagpki/issue/2618 allow CA to process pre-signed CMC renewal cert requests

    Ticket#2618 feature: pre-signed CMC renewal request
   
    This patch provides the feature implementation to allow CA to process pre-signed CMC renewal requests. In the world of CMC, renewal request are full CMC requests that are signed by previously issued signing certificate.
    The implementation approach is to use the caFullCMCUserSignedCert with the enhanced profile constraint: UniqueKeyConstraint.
    UniqueKeyConstraint has been updated to disallow renewal of same key shared by a revoked certificate.  It also saves the origNotAfter of the newest certificate sharing the same key in the request to be used by the RenewGracePeriodConstraint.
    The profile caFullCMCUserSignedCert.cfg has been updated to have both UniqueKeyConstraint and RenewGracePeriodConstraint.  They must be placed in the correct order. By default in the UniqueKeyConstraint the constraint parameter allowSameKeyRenewal=true.

Thanks,
