Fixed vnfapi install issue

Fixed issues with vnfapi install:
 - Resolved issue installing vnftools by converting to blueprint
 - Resolved issue not finding RPC implementation of vnfapi by fixing
   dependency feature vnftools, and by converting vnfapi to blueprint.

The root cause in both cases was probably something wrong with the
provider configuration, but it was simpler (not to mention more
maintainable) to just convert from config to blueprint.
