glusterd: Fix to log command status at the appropriate time
PROBLEM: In the existing implementation, the success/failure of execution of a command is decided (and logged) in glusterd handler functions. Strictly speaking, the logging mechanism must take into account what course the command takes within the state machine before concluding whether it succeeded or failed. FIX: This patch attempts to fix the above issue for vol commands. The format of the log message is as follows: for failure: <command string> : FAILED : <cause of failure> for success: <command string> : SUCCESS APPROACH (in a nutshell): * The command string is packed into dict at cli and sent to glusterd. * glusterd logs the command status just before doing a "submit_reply", which is called (either directly or indirectly via a call to glusterd_op_cli_send_response) at 2 places for every vol command: i. in handler functions, and ii. in glusterd_op_txn_complete In short, the failure of a command in the handler implies the command has indeed failed. However, its success in the handler does NOT necessarily mean the command succeeded/will succeed.
