Provide a way to change the 'logical' state of multiple shards atomically

Provide a way to change state of multiple shards atomically perhaps through the Collection API.
This command should take a map (in some format) of <Shard, State> and update the state of the Shards (Slice) to the corresponding state atomically.

This is the 'slice' or 'logical' state rather than the per physical shard state.
