Retry on aborted connections

[jcass77]

The radio stream stops playing when the connection is reset, and the log contains:

Please file a bug.

It might be possible to have Mopidy-TuneIn retry a couple of times before giving up, which should make it much more robust.

pydora follows a two-pronged strategy of retrying connections at least once, and also handling specific HTTP-related exceptions with the time between retries increasing exponentially.

It seems to be working well for the Mopidy-Pandora backend and I haven't had any connection issues since - not sure if it can be ported.

Would like to see this. I get disconnected after a while but I can play again manually. Retry will be good option.

Any chance this gets fixed? I basically have the similar problem that the plug-in collapses if the opposing streaming server doesn't reply in time:

Playback stops and can not be turned back on. One is forced to restart the mopidy (systemctl restart mopidy).

Isn't that an actual connection error? What is this extension supposed to do here? I'm not interesting in supporting this but will merge a decent PR
