Title:
  add request timeout handling for Mellanox Neutron Agent

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  Mellanox Neutron Agent communicates with eswitchd to execute vports discovery 
and configuration.
  In case eswitchd is not reachable, request timeout is received. The current 
handling of the timeout was to mark out of sync flag, flush the agent cache and 
try again. This behavior leads to miss the removed vports and their 
configuration is not removed. The request timeout was received in case group of 
VMs was removed at once. The solution is to add number of retries with 
increasing waiting time in case  request timeout is received. If request 
timeout persists, exit the agent process.
