Title:
  DVR: regression with router rescheduling

Status in neutron:
  Fix Released

Bug description:
  L3 agent may not fully process dvr router being rescheduled to it which leads to loss of external connectivity.
  The reason is that with commit 9dc70ed77e055677a4bd3257a0e9e24239ed4cce dvr edge router now creates snat_namespace object in constructor while some logic in the module still checks for existence of this object: like external_gateway_updated() will not fully process router if snat_namespace object exists.

  The proposal is to revert commit
  9dc70ed77e055677a4bd3257a0e9e24239ed4cce and the make another attempt
  to fix bug 1557909.
