Disable cpu pinning & L3 HA features

* CPU pinning: tests have no support for dedicated CPU policy, so
  enabled pinning causes general performance impact
  [https://docs.openstack.org/nova/pike/admin/cpu-topologies.html]
* L3 HA routers:
  - doesn't catch l3-agent failure, relies only on
    HA network state to spot failure
  - failover process only retains the state of network
    connections for instances with a floating IP address
  - incompatible with DVR mode
