Strategy & source metrics

[dmorn]

A strategy needs metrics to make decisions. At the moment we already instrument the program with the metrics component. Instead of duplicating the source metrics inside the source itself (the aim was to then retrieve the values with the Value(interface{}) interface{} function), provide a way to retrieve and control the lifetime of the source's metrics from the metrics component, which can then be used by the different strategy implementations.

It is possible to retrieve the metrics through https://godoc.org/github.com/prometheus/client_golang/prometheus#Gatherer

As we can control booster remotely, and a strategy would nevertheless take the metrics from our exported metrics package, we could:

• create a strategy that gives connections to sources using a configurable windowing system or anti congestion control mechanism
• add an endpoint to allow to configure this strategy remotely

This way tools that manage how booster behaves could be developed separately!
