Adds a registration function to metadata which allows plugins to register resources to be garbage collected. These resources allow defining resources types which are ephemeral and stored outside the metadata plugin without extending it. The garbage collection of these resources will not fail the metadata gc process if their removal fails. These resources may be referenced by existing metadata store resources but may not be used to reference metadata store resources for the purpose of preventing garbage collection.

There was a problem hiding this comment.
Basically, the change looks good.
The development doc is wanted I think~ It is not blocked.
Ensure the registered resource type does not conflict with existing resource types or over the max. Signed-off-by: Derek McGowan <[email protected]>

This is split out from my work on the new image transfer service which will use this for tracking progress streams. This could also be used in the implementation of a mount and network manager after the sandbox API is merged.
