Pr ixia reuse session extra fix (#416)

* QUAGGA_CONFIG update

QUAGGA_CONFIG there is no policy (route-map) defined for peer-group IXIA. Due to that it is not able to receive routes In/Out. If we add “no bgp ebgp-requires-policy”, it advertises and receives the routes from other peers and traffic flows fine.

* Fix for continuing with new session if ixnetwork session aborted abnormally

* flake8 fixes
