"""Handling of MAAS API credentials.
The API client deals with credentials consisting of 3 elements: consumer
key, resource token, and resource secret. These are in OAuth, but the
consumer secret is hardwired to the empty string.
Credentials are represented internally as tuples of these three elements,
but can also be converted to a colon-separated string format for easy
transport between processes.
