Integrate coldfront-plugin-api

- Introduces patches/01_add_api_urls.patch which works around
  ubccr/coldfront#518 and is applied on
  container build.
- Introduces /api/allocations/ which returns a list of all
  Resource Allocations that are active. This API requires
  admin permissions to query (setting the staff flag after a first
  failed query)

Some notes:
- To authenticate to the API as a client, you must set `openid`
  as a default scope for the authenticating client and associate a
  mapper that maps `uid` to the User property `username`.
  You must also set the `email` field for the client user in
  Keycloak.

Closes nerc-project#84
