Fix of reading payload in request and response
Reading the request response payload leads to an exception, adding a buffer class which enables multiple reads. Also adding logging of AAF. Check if response not sent Check if someone else didn't already flush the response Changing interpretation of role Letting users with advanced roles run non-gremlin queries. Adding logging. Change-Id: If5c9c94b63c3203d2193b43eed5fcd5993f0c4fa Issue-ID: AAI-1762 Signed-off-by: Kajur, Harish (vk250x) <vk250x@att.com>
