Fixed a bug that relates to dropping foreign servers on worker nodes. Previously, when we had to delete an old shard, we issued a foreign server drop command to the worker nodes that had the shard. We hard-coded the server name as file_server, and this caused an issue with any foreign data wrapper other than file_fdw. This change fixes that issue.
