Find Jenkins worker IPs?

[phillipj]

Any hints finding all Jenkins worker IPs?

Asking because we want to start whitelist the Jenkins hosts allowed to post inline PR status updates via the github-bot. The bot already has whitelisting implemented, but the list of IPs is currently not being set when starting the bot.

Refs nodejs/github-bot#142

@maclover7 were we able to restrict this to just the jenkins-workspace hosts? Otherwise it's going to be annoying whenever we add and remove IP addresses from the list. This happens every other week.

The IP addresses are here: https://github.com/nodejs/build/blob/master/ansible/inventory.yml, see the two jenkins-workspace hosts near the bottom, hopefully we can restrict it to just those. Otherwise you're going to have to add everything under the test section except for the requireio hosts which will come from the single ip address that resolves from vagg-arm.nodejs.org.

Yeah, the only machines running post-build-status-update and working with the bot should be jenkins-workspace machines as defined here.

Thanks! Opened #985 to provide those two current IPs to the bot.
