improvement: systemvm slow operations
On our setup we had issues with vrouters when a large number of VM were
created at once.
The vrouters try to arping the gateway (to refresh the ARP cache I
suppose), but in some case it take too much time and the vrouters got killed
for being unresponsive.
The following patches attempt to solve this by:
* a96ab18f, 8908371b defensive fix, maybe a bug?
* fce10c55 do not block on arping command
This patch has been running for a month on our test environment and seems
to solve the initial problem.

systemvm: ips.json without gateway
The file "/etc/cloudstack/ips.json" is generated with a gateway at
"None" even when the gateway is present in the input "cmd_line.json".
