Monitor multiple streams

[jooola]

As an exporter I would expect a 1:1 relation to an icecast server, but maybe it's worth allowing to monitor multiple icecasts stream/stats.

I don't know how much complexity it would add to allow multiple stats endpoints.

@paddatrapper What use cases would you have ?

Our use case is also 1:1 with a single icecast server

So I think keeping a 1:1 relation to an icecast server is best, though Icecast can handle multiple different streams at once, so we might want to be able to listen to multiple streams at once, but only track a single stats endpoint.

Leaving this as it is, if the need show up I might implement this.
