Addresses #5935.
The DROP SHARD command takes the ID of the shard and drops it
from both the meta store, and the data node. Shard data is deleted
on the node.
If the shard to be deleted is the last shard in the shard group,
then the shard group is marked as deleted.
Attempting to delete a shard that does not exist will not return an
error.
