FEAT: Add dspot-pipeline dockerimage (#802)

[henry-lp]

Hi :), this is a broken down PR for this original PR (#832).

How to use:

First pull and run the ActiveMQ server image

  docker pull webcenter/activemq:5.14.3
  docker run -d --net=host webcenter/activemq:5.14.3

Then go to the server page to make sure that it's up http://localhost:8161.
Go into kubernetes-support/Dpipeline-dockerimage and build the dspot-pipeline image and run it.

  cd kubernetes-support/Dpipeline-dockerimage
  docker build -t dspot-pipeline .
  docker run --net=host -e ACTIVEMQ_HOST=localhost dspot-pipeline

Now you can see in your server page that there is one consumer on your Dpipeline queue. Next is to use publisher.py to send build id for the pipeline to do some work.

  cd kubernetes-support/queue-for-buildids
  python publisher.py -d /queue/Dpipeline 560288647

This will send a travis build from this repo branch with_dspot to run . Now you should see some output.

Appearantly we are failing due to unused imports according to java checkstyle :) .

Hi @tailp

I did introduce this style error (this is what happens when you push directly on the master branch)

Thank you for fixing it.

Thank for the docker image.

Ready to merge?
