Gratia v2 Development

During the 20:00 run on 1/25 it was observed that the call to describe_spot_instance_requests() was timing out after five minutes for each instance (the data is cached after the first successful call). This caused the probe to take over an hour to run.

The spot instance request data is only used for the bid price, which is non-essential information, so maybe the call should be skipped after a timeout.

Log attached. As temporary fix disabled bid price lookup.
