Move logging from _request() to raw_request()

rest_client log all request and response data when called via its get,
post, put, delete method etc because logging is done in self._request().

But when any service client make API request via raw_request() then logging
is not done.

_request() method internally call the raw_request() method so moving the
logging from _request() to raw_request() will not effect existing behavior.
