Refactor Status Updater to be resource agnostic

[kate-osborn]

Currently, the status updater is aware of what resource it is updating the status of. This makes it difficult to extend because for each new resource we add support for, we have to modify the status updater.

See this comment thread for more context.

A/C:

• the status updater is not aware of which resource it is updating the status of

@mpstefan I think this is high-priority tech-debt since adding policies will further strain our status updater component.
