Public bug reported:
The wsgi server used in most if not all openstack services currently
has keepalive=True by default thus keeping connections open after each
request. This can cause problems when using load balancers in front of
these services e.g. connections for requests that take a long time can
get closed in the load balancers once a timeout has expired. This can
then cause issues if a client performs a request using the same source
port as a previous request that is not closed in the LB but still open
in the server due to TCP packet sequecing in the LB and the new client
not expecting the connection to already be open. So, it would be useful
to be able to disable wsgi keepalive.
