The proposal to merge ~chad.smith/cloud-init:feature/azure-network-on-boot into cloud-init:master has been updated.

Commit message changed to:

azure: allow azure to generate network configuration from IMDS on each boot

Azure datasource now queries IMDS metadata service for network configuration at
link local address http://169.254.169.254/metadata/instance?api-version=2017-12-01.
The azure metadata service presents a list of macs and allocated ip addresses
associated with this instance. Azure will now also regenerate network configuration
on every boot because it subscribes to EventType.BOOT maintenance events as well as
the 'first boot' EventType.BOOT_NEW_INSTANCE.

Also refactor _get_data into 3 discrete methods:
  - is_platform_viable: check quickly whether the datasource is
    potentially compatible with the platform on which is is running
  - crawl_metadata: walk all potential metadata candidates, returning
    a structured dict of all metadata and userdata. Raise InvalidMetaData
    on error.
  - _get_data: call crawl_metadata and process results or error. Cache
    instance data on class attributes: metadata, userdata_raw etc.
