Initial work on quota using new proxy.
Work on a new quota SPI for Apigee that works in three modes:
Remote, using the old policy-based protocol.
Remote, using the new Node.js-based protocol.
Local, using apigee-access.
Update oauth to use new protocol as well as old one, and
apigee-access if supported on the server.
Fix some problems with the quota tests run remotely.
Update package.json for merge.
Update server-side tests with Mocha tests that run on the server
and directly hit the SPI.
