Bug Description

Sometime we hit the issue, where ECMP routes are not created if same static routes are added on 2 VMIs on different computes.

This issue is not always seen, and when in problematic state, restarting the agent recovers from the issue.

currently I'm hitting it in my setup:

look for static route prefix 9::/64.
http://nodec62.englab.juniper.net:8085/Snh_Inet6UcRouteReq?x=1
http://nodec12.englab.juniper.net:8085/Snh_Inet6UcRouteReq?x=1

horizon: http://nodec64.englab.juniper.net/horizon/admin/instances/
contrail UI: https://nodec64.englab.juniper.net:8143/#p=config_net_ports

steps:
-create 2 VMs on diff computes with dual stack.
-create a static route table with v6 prefix(9::/64) and add it on both VMIs
- ECMP routes should be created for 9::/64

Increase ARP and ND retries up to 5 minutes

Whenever the VM is spawned Agent sends ARP request for v4 and ND request for v6.
Increase the retries for these requests up to 5 minutes, with each retry after every 2 seconds.
