log.SetTarget creates the log file under log directory using golang os package. Whenever code sets the log directory, it needed to call SetTarget to create the actual log file under that directory. In the recent logger changes, InitLogger by default set the log directory to the current folder. This created the log file in the current folder. The code then set the log directory to a different location without a subsequent call to log.SetTarget. This resulted into the logger to not find the actual log file in the set log directory.
This fix updates the logger InitLogger function to accept the log directory to create the file in correct log directory. To avoid having such issue, this fix also combines the function calls to set log directory and set target into a single function. This prevents any out of order calls resulting into such issue.
