Improve log information when exception is caught in Orch2 class (#3401)

What I did
Add the information regarding which class the exception is originated from when Orch2 catches an exception.

Why I did it
An Exception was thrown, and the error log given was:
ERR swss#orchagent: :- doTask: Logic error: map::at 
This gives almost no information on where the exception happened.
