Merge pull request #178 from alphagov/use_fog_1_21

Use fog 1.21.0 (and vcloud-core 0.11.0)
Remove all launcher files

This guts this repository - that is the plan. Aim is for vCloud Tools to be a meta-gem that pulls in the other gems (need to move utils out before that happens).
Update README

- Change VCloud to vCloud
- Update some links, including the link to the published launcher gem
- A few other tidy-ups
No need for jenkins_integration_tests

There is now no Rakefile and no integration tests so no need for the jenkins_integration_tests script. I have also removed the integration test jobs in Jenkins.

This also removes `bundle exec rake` from `jenkins.sh` for similar reasons. However, the the script will be required when the step is made to meta-gem so no need to remove it here.

Update for recent changer to launcher related files

In the past the vcloud-tools included vcloud/launch.rb and a few other
files.  These recently moved to their own gem vcloud-launcher.

Since that change though this repo needs to be updated to include the
dependency and to account for some changes from vcloud/launch to
vcloud/launcher etc.  This commit does that.
