Hook invoked by ReceivePack after all updates are executed. 
 The hook is called after all commands have been processed. Only commands with a status of Result.OK are passed into the hook. To get all commands within the hook, see BaseReceivePack.getAllCommands(). 

Any post-receive hook implementation should not update the status of a
command, as the command has already completed or failed, and the status has
already been returned to the client.

Hooks should execute quickly, as they block the server and the client from
completing the connection.
