Partial-Bug: #1378125
Enhance server manager logging

1)Server manager debug logs, will emit filename,linenumber and function
Alos logger.conf is allowed to hide/show detailed fields such
file,function,line number.
2)Transaction logger is corrected to print URI, query string and any
post data if any.
3)Clean the code so that evaluvation of params go into a single method

Testting Done:
Make sure all command are working and logs are emitted for both debug
and transaction logs.
