potential fix for attaching router with external network gateway

In the CI environment, whenever testcases attaches a router with
external network gateway sometimes it throws the error "No more IP
addresses available on network". This could be due to stale floating
ip's exist in the deployment which is cleaned up now before executing
sdnvpn testsuite.
