DataSourceMAAS reads instance information from MAAS.
Given a config metadata_url, and oauth tokens, it expects to find
files under the root named:
instance-id
user-data

MAAS doesn't provide a real instance-id, and if it did, it is
still only available over the network. We need to check based
only on local resources. So compute a hash based on Oauth tokens.t

Read the maas datasource at seed_url.
read_file_or_url is a method that should provide an interface
like util.read_file_or_url
Expected format of seed_url is are the following files:
* <seed_url>/<version>/meta-data/instance-id
* <seed_url>/<version>/meta-data/local-hostname
* <seed_url>/<version>/user-data
If version is None, then <version>/ will not be used.
