Bugs fixed

The following bugs are fixed in this release.

Topic	Description
Netty router unresponsiveness due to buildup in the pooled connections CORERT-219	Resolved issues which caused a connection leak when the client disconnected even before API responses were delivered.
State machine errors in Netty router logs causing hung router CORERT-201	When a client sent back-to-back requests on a connection without waiting for a response, the Netty router seemed to hang and not process any requests. A new HTTPServer.pipelining.enabled property in router.properties for the Netty router lets you control HTTP pipelining. The following values describe the behavior: false (default) - If Multiple requests are received, the router returns an error indicating the pipelining attempt and closes the connection. true - The router handles one request at a time by buffering the requests into a pending queue. Responses to each request are sent out in the same order as they arrived. In cases where a responses needs a connection closure, the connection is closed immediately and no responses are sent for subsequent requests.
CLOSE_WAIT messages CORERT-188	Resolved issues with CLOSED_WAIT messages that aren't properly closed.
Message processor closing connections while router tries to reuse connections from the pool CORERT-114	Resolved the issues causing pooled connection to be closed in certain error conditions.
5xx errors on responsesAPIRT-342	5xx HTTP errors occurred in situations where a response was complete according to the HTTP specification (no Content-Length or chunked encoding in target endpoint responses). Edge now treats those responses as complete.
