Notes:
* This datasource replaces previous NoCloud datasource for LXD.
* Older LXD images may not have updates for cloud-init so NoCloud may
still be detected on those images.
* Detect LXD datasource when /dev/lxd/sock is an active socket file.
* Info on dev-lxd API: https://documentation.ubuntu.com/lxd/en/latest/dev-lxd/

Any CONFIG_KEY_ALIASES which affect cloud-init behavior are promoted

Perform a number of HTTP GETs on known routes on the devlxd socket API.
Minimally all containers must respond to <LXD_SOCKET_API_VERSION>/meta-data
when the LXD configuration setting `security.devlxd` is true.
When `security.devlxd` is false, no /dev/lxd/socket file exists. This
datasource will return False from `is_platform_viable` in that case.
Perform a GET of <LXD_SOCKET_API_VERSION>/config` and walk all `user.*`
configuration keys, storing all keys and values under a dict key
LXD_SOCKET_API_VERSION: config {...}.
In the presence of the following optional user config keys,
create top level aliases:
- user.user-data -> user-data
- user.vendor-data -> vendor-data
- user.network-config -> network-config
:param api_version:
LXD API version to operated with.
:param metadata_keys:
Instance of `MetaDataKeys` indicating what keys to fetch.
:return:
A dict with the following optional keys: meta-data, user-data,
vendor-data, network-config, network_mode, devices.
Below <LXD_SOCKET_API_VERSION> is a dict representation of all raw
configuration keys and values provided to the container surfaced by
the socket under the /1.0/config/ route.
