MCT Adaptation issues: Realtime subscriptions <Cubsat issue> #213
Description
MCT only makes queries for channels that are actively in view. In realtime mode, MCT subscribes to channels in active view instead.
The MCT adaptation is currently subscribing to a websocket and receiving all telemetry on that socket then filtering for subscribed channels with a loop.
AIT core should manage the subscribed channels for each client: NASA-AMMOS/AIT-Core#357
MCT adaptation should use filters instead of loops for received telemetry.
MCT adaptation should pass subscriptions on to AIT-Core to be managed there instead of clientside.
