mon: Init Loggings for ConnectionTracker.cc & Added more loggings to ElectionLogic & Elector

Problem:

Currently there are not ConnectionTracker logs,
therefore it is really hard to debug

Solution:

Enable loggings for most functions in ConnectionTracker.cc
Most of the logs are in debug_mon = 30.

Also Added some logs in Elector and ElectionLogic
so that debugging will be easier in the future.
