Cleanup of signature_utils code

Registered by Dane Fichter on 2016-08-11

Glance and Nova contain nearly identical digital signature modules. In order to reduce the effort required to maintain this code and to eliminate the possibility that the modules diverge, we propose removing this code and instead using the cursive library. The cursive library is a Stackforge project which implements OpenStack-specific verification of digital signatures.

We are targeting this cleanup for the Ocata-1 sprint.

    Use cursive for signature verification

I'm going to approve this for Pike as a code cleanup effort so we reduce duplication of efforts between nova and glance. There is CI testing on this code path in the nova experimental queue now too:
