Relocate ruby code to src/ruby
Update bundler, improve install speed

- Use latest version of bundler from rubygems rather than Ubuntu
  packaged version (1.3.5)
- Parallelize installation of cikl-api and cikl-worker by adding '--jobs=7' to
  'bundle install' calls.
Gemify cikl-worker and cikl-api

- Allows it to play nicer with bundler
Add missing require for grape-swagger
Fix handling of integration tests

- Elasticsearch was being started even when integration tests were
  supposed to be disabled
Remove Bundler.require, causes problems

-  Bundle.require requires all gems in the specified Bundler group. This
   is unneeded for our project, and actually causes issues if
   :development is specified.
