When running tempest full smoke test, each time tempest.tests.compute.servers.test_server_rescue.ServerRescueTestJSON and tempest.tests.compute.servers.test_server_rescue.ServerRescueTestXML would get an BadStatusLine error when delete a floating ip.
Did a packet capture and found out that ha proxy sent tcp rst on receiving the deleting the floating ip request.
However, it can not be reproduced by running the particular test manually. Need more haproxy log for investigation.

haproxy closes the tcp connection after client timeout, which was 50s, so later when tempest/httplib2 sent floating ip delete request, the tcp connection was not there, hence the tcp rst.
Try increasing the timeout to 100s to see what happens.
