Current LogFormatter prints the following information

Though this is good information, it does not provide additional information like
createSession: which ip created the session and its time out
set|get|delete: the path and data
create: path created and createmode along with data

We can add additional parameter -detail and provide detailed output of the transaction.

Outputting data is slightly tricky since we cant print data without understanding the format. We need not print this for now.
