REQ-321 CMPv2 Enhancements for R7

REQ-321 is for DCAE project, to integrate with AAF/CertService components created during the ONAP/Frankfurt release.

Actually, we don`t expect to do changes in AAF/CertService to support that requirement, worst case we might find a bug in the AAF/CertService implementation, which would have to be fixed.

There is a potential dependency -> if we find bugs in CertService. If we do so, we`d be able to fix them without touching the rest of AAF code, as CertService is completely independent from other components of AAF (it simply lives in AAF project, but it could live anywhere else too).

We can do relevant documentation/release note changes for AAF/CertService, if any bugs will be found and fixed.

CMPv2 CertService small enhancements (configurable artifacts output type) and introduction of new API to update certificates (best effort)
