Write tests to cover spawning in all languages using microservice-examples repo

[Marak]

We should have an integration test that iterates through all supported programming languages and attempts to assert the responses of all hello world / echo services located in https://github.com/Stackvana/microservice-examples, per language.

These test will ensure the target language is working and supported on the system. ( Currently we only test with bash and node )

[Marak]

This is now resolved and merged into master.

Only caveat is that travis-ci doesn't easily support multiple languages in one test.

There is a solution available at: travis-ci/travis-ci#4090, but this will require a bit of tinkering in the .travis.yml file. Until then, these tests have been commented out ( but should work locally if you have language installed in system )

Re-opening until Travis-CI issue is addressed

[Marak]

It seems like Travis-CI has closed the issue and not posted any updates on this.

I'd really like to get the multi-language tests working in the CI.

Suggestions are welcomed.
