Fixes

Compilable docs for IBMMQ and documentation update

Purpose

1. Add ibmmq docker image
2. Add ibmmq clients dependency
3. Add test classes: scaladsl and javadsl

Background Context

I currently building integration at work and I use alpakka/jms connector. I saw differences between versions 1.0-M1 and 1.0-M2. Also there is opened issue for doc update.
I decided to help. I am looking forward for release 1.0

References

ref: #1328

Looking good. You will also need to modify .travis.yml to start the ibmmq as well before running tests:

alpakka/.travis.yml

Line 39 in 472a9b5

- PRE_CMD="docker-compose up -d amqp"
