NoDevserverInSubnet for subnet 172.22.38.0/23 alerts

Project Member Reported by dgarr...@chromium.org, Dec 14 2017 
This staging alert could be improved.

First, it contains this entry:

name: NoDevserverInSubnet
current value: 0.002824451345755694

Which doesn't make much sense to me.

Second, it would be very helpful to know which devservers it thinks exist in the range, and how many devservers it thinks SHOULD exist.

Comment 1 by dgarr...@chromium.org, Dec 14 2017 

Checking atest server list for 172.22.38.0/23, I see the following devservers:

chromeos3-infra-devserver.cros.corp.google.com
chromeos3-infra-devserver1.cros.corp.google.com
chromeos3-infra-devserver2.cros.corp.google.com
chromeos3-infra-devserver3.cros.corp.google.com

This alert would be expected to fire if too many devservers are offline, or if they are all running, but too many DUTs have been added to the subnet.

Ah.... chromeos3 is not one of our main labs.

Maybe we should blacklist it in this (and other devserver related) alerts?

I think those are the machines that are always unreachable whenever I run commands across our whole prod fleet.  Should we be tracking them in our server database if they are unreachable for us?

I show the following devservers as online:

chromeos3-infra-devserver	172.22.39.161
chromeos3-infra-devserver1	172.22.39.162
chromeos3-infra-devserver2	172.22.39.163
chromeos3-infra-devserver3	172.22.39.164

I think these should be added to the tracking list.
