[Xiao Li Xu]

 [Summary]
 LB_NFV KiloV1 :the default session limit is 2000 rather than unlimit

 [Topo]
        RDO-Kilo
        CentOS 7.1

 [Description and expect result]
 if we don't config session limit , the expect the session shoule be not limit

 [Reproduceable or not]
   it is easy to recreate.

 [Recreate Steps]
if don't config session-limit , the default session limit is 2000 , but the GUI show the session limit is -1, as our common understanding , the negative number mean unlimit .
so this issue should be fixed
