Set vif_details to reflect enable_security_group

While plugging vif, VIFDriver in Nova follows "ovs_hybrid_plug" and
"port_filter" in "binding:vif_detail" which is passed from Neutron, but
those are always true.  This patch make ML2 OVS mech driver set those
param depends on enable_security_group flag.  It enables users to avoid
ovs_hybrid plugging.

This patch also fixes the same issue in the following plugins/drivers:
  * NEC Plugin
  * BigSwitch Plugin
  * Ryu Plugin
  * ML2 Plugin - OFAgent Mech Driver

NSX: Make conn_idle_timeout configurable

If there is a loadbalancer that sits between NSX and neutron usually it has
a default http_timeout on long lived http_connections. This can cause
connections that have not been used from neutron to nsx to be reset after
sometime. This patch makes the amount time we wait to reconnect the connection
configurable so one can set it to match the balancer timeout to avoid having
to try the connection if the loadbalaner has already timed it out.

Remove use_namespaces from RouterInfo Property

The use_namespaces property is a property of the agent, not the
router.  The router doesn't need to know if namespaces are in use by
the agent.
