C++ Add Measurement Queue class for Controllers

Working measurement queue code.

• depends on !718 (merged) for using metrics as measurement condition
• should have a timeout for receiving a metric
• maybe it should be possible to define the comparison operator for the metric, right now it's >= fixed
• could use !716 (merged) for validation of measurements
• should think about how to detector & treat failing satellites during running - probably check global state in await_condition periodically?
• between queues we should do a full initialize again, otherwise scanned parameters will stick with last value of scan for next queue

and requires UI (separate MR).
