Evaluate CircleCI (dropwizard#1883)

* Increase read timeouts for end-to-end tests
* Evaluate CircleCI

Add support for running tests on CircleCI. The idea is too have an
additional CI server for running tests  on the Linux environment,
because in recent times we have had some issues with Travis CI.
