Iss #132 - Update API to use shared projects services

In the API common lib, there is a new efservices module which provides
access to the Accounts and Projects service in a standardized way. This
PR removes most of the code associated with previous projects logic and
keeps a helper to help with formating and filtering the data.

This currently uses a snapshot version, so there will need to be a
release for this code to go live and be stable.
