cli: add cloud-init query subcommand to query instance metadata
Cloud-init caches any cloud metadata crawled during boot in the file
/run/cloud-init/instance-data.json. Cloud-init also standardizes some of
that metadata across all clouds. The command 'cloud-init query' surfaces a
simple CLI to query or format any cached instance metadata so that scripts
or end-users do not have to write tools to crawl metadata themselves.
Since 'cloud-init query' is runnable by non-root users, redact any
sensitive data from instance-data.json and provide a root-readable
unredacted instance-data-sensitive.json. Datasources can now define a
sensitive_metadata_keys tuple which will redact any matching keys
which could contain passwords or credentials from instance-data.json.
Also add the following standardized 'v1' instance-data.json keys:
- user_data: The base64encoded user-data provided at instance launch
- vendor_data: Any vendor_data provided to the instance at launch
- underscore_delimited versions of existing hyphenated keys:
instance_id, local_hostname, availability_zone, cloud_name
