------------------------------------------------------------------

So the reason i have put some info in is because  we usually want to run the debug only for
some period of time and during that time period we want to be able to figure out what exactly
is happening.
Also, the information is not technically coming from the client since many usecases might
be where the hadoop key shell or some other process is making the call and we want to see
if there is a bug in the KMS side or in the incoming messages.

is the main class that serves KMS http requests. There're currently no logs at all, making
trouble shooting difficult.
