Public bug reported:

        [Summary]
	LB_NFV:KiloV1 ,the maxconn should be created on  global section of  HAprxy config file

	[Topo]
        Openstack version :RDO kilo 
        OS version :centOS 7.1
 

	[Description and expect result]
	the maxconn should be created on  global section of  HAprxy config file

	[Reproduceable or not]
	 it is easy   to recreate.

	[Recreate Steps]
after create a LB with max-session limit , the maxconn was not wrote to global section of HA proxy config file ,
 this max config will effect our max session number ,because file-handle number was less than expect

log
following is default config ,the max open file is 4031
