CLOUDSTACK-9583: VR: In CsDhcp.py preseed both hostaname and localhost to
resolve to 127.0.0.1
The VR executes a ip route flush command as part of configurations. This
command performs a
DNS lookup on the VR hostname. Since the VR does not have a DNS entry, the
ip command would
wait 5 seconds before timing out and executing the flush operation. This
fix adds the VR
hostname to /etc/hosts mapped to 127.0.0.1 to answer the DNS lookup –
reducing the
execution time.

> It is observed that 'ip route flush' was timing out after 20 seconds with
> the error that can't resolve the name of the vrouter. Since this is done for
> each rule for a router with a lot of rules, adding the entry to hosts file
> fixes it and the router provisioning is observed faster.
