state: add Unit.WatchStorageInstances 
We'll need to watch storage instances from the
uniter, to trigger storage hooks. We'll also use
it in the storage provisioner.

worker/uniter: reimplement storage as operation 
We introduce a new StorageChanged operation, and
ModeStorageChanged. When storage changes are observed
in ModeAbide (alive), we execute a StorageChanged
operation.

The StorageChanged operation is responsible for
comparing reportedly changed storage instances to the
persistent local state, and enqueuing storage hooks.
Storage hooks are responsible for updating the storage
attachment info in persistent local state once
committed. ModeContinue has been updated so that if
there is more than one changed storage instance, it
will resume handling changes by reinvoking
StorageChanged.
