[jm66]

Describe the bug

Updating a content library storage backings does not work with the following code:

library_id = '<valid_lib_id>'
datastore_mo_id = '<valid_ds_id>'

update_spec = LibraryModel()
update_spec.storage_backings = [StorageBacking(type=StorageBacking.Type.DATASTORE, datastore_id=datastore_mo_id)]
self.client.local_library_service.update(library_id, update_spec)

Reproduction steps

1. Update content library backings with the following code:

library_id = '<valid_lib_id>'
datastore_mo_id = '<valid_ds_id>'

update_spec = LibraryModel()
update_spec.storage_backings = [StorageBacking(type=StorageBacking.Type.DATASTORE, datastore_id=datastore_mo_id)]
self.client.local_library_service.update(library_id, update_spec)


2. Storage backings not updated and no error is thrown.

Expected behavior
