[atlas] Probe uptime?

Hi Max,

ctr-nue19 was rebooted around 11 o'clock UTC because it was not responding.

The logic is following: If a controller doesn't send heartbeats for more 
than 2 hours it is excluded from the list of available controllers.
The algorithm that assigns a probe to a controller tries to assign 
probes the controller it was connected last time. So your case your 
probe needed to migrate to another controller (ctr-ams07) after 2 hours 
of trying to connect to the last controller.

It is not necessarily a downtime. It is stated here int the report as 
the disconnection time. During that time your probes does measurements 
but it doesn't sent results to controller.

We are introducing the probe uptime metrics, but it is still in the 
making and not exposed to users yet and not included into the billing.
