Datasources: Formalize DataSource get_data and related properties.
Each DataSource subclass must define its own get_data method. This branch formalizes our DataSource class to require that subclasses define an explicit dsname for sourcing cloud-config datasource configuration. Subclasses must also override the _get_data method or a NotImplementedError is raised. The branch also writes /run/cloud-init/instance-data.json. This file contains all meta-data, user-data and vendor-data and a standardized set of metadata keys in a json blob which other utilities with root-access could make use of. Because some meta-data or user-data is potentially sensitive the file is only readable by root. Generally most metadata content types should be json serializable. If specific keys or values are not serializable, those specific values will be base64encoded and the key path will be listed under the top-level key 'base64-encoded-keys' in instance-data.json. If json writing fails due to other TypeErrors or UnicodeDecodeErrors, a warning log will be emitted to /var/log/cloud-init.log and no instance-data.json will be created.
