catch the correct exception for alarm not found case

Issue:
for the alarm_show/alarm_delete/event_show api, if the input UUID
string is not valid, http server side will return error code 500
(Internal Server Error), due to the error code is not set correctly.
Solution:
Correct the error code in server, and add client code to handle
"HTTP 404 - Not Found" error code correctly.

Test:
Run "fm alarm-show/alarm-delete/event-show" with valid/invalid
UUID, and the response is correct. For invalid UUID, response
string will like below. "xxx" for the invalid UUID string.
"Alarm not found: xxx"
"Event log not found: xxx"
