Backend plugin for RA activities.
The `ra` plugin provides access to the CA to issue, retrieve, and revoke certificates via the following methods:
* `ra.check_request_status()` - check certificate request status. * `ra.get_certificate()` - retrieve an existing certificate. * `ra.request_certificate()` - request a new certificate. * `ra.revoke_certificate()` - revoke a certificate. * `ra.take_certificate_off_hold()` - take a certificate off hold.
