Jms does not handle failures

[eirirlar]

When attempting to stream messages to a jms topic that has gone down and come up again, writing fails silently.

This should probably be documented along with advice on how to handle the situation.

Note that not silently, as streams have one failure mode - they'll signal error through the stream, if you add a .log() stage it would log the error, otherwise it assumes you're handling it in the pipeline.

But yes, this should be documented but perhaps in separate patterns section.

Ways to handle it are:

• Retry https://github.com/akka/akka-stream-contrib/blob/master/contrib/src/main/scala/akka/stream/contrib/Retry.scala
• host in Actor and bind lifecycle with it (my fav to be honest, could use some examples)

This is now fixed with #1227 and #1252.
