Some minor refinements in CCSDK SLI Northbound

Fix few Critical/Major sonar issues in CCSDK SLI Northbound module
* Remove useless parentheses
* Remove useless assignment to local variable
* Use built-in logger method string formatting instead of string concatination
* code indentation
* Replace for loop with foreach
