This patch provides basic support for DRM transport key rotation
described
in
http://pki.fedoraproject.org/wiki/DRM_Transport_Key_Rotation
This patch provides implementation for tickets:
- 729 - CA to include transport certificate when submitting
archival request to DRM
- 730 - DRM to detect presence of transport certificate attribute
in submitted archival
request and validate transport certificate against DRM's
transport key list
- 731 - DRM to provide handling for alternative transport key
based on detected
and validated transport certificate arriving as a part of
extended archival request
