The pypi package 'docker-py' [1] has been renamed to 'docker' [2].
It is better to move to the new 'docker' package because the old
package will be deprecated and all the new features will go into
the new package only.

Package 'docker' has been added to requirements [3]. The old
package 'docker-py' is still allowed to be in the global requirements
during the transition period but it should be removed after all or
most of the projects finsih the migration.

 - Updated Ubuntu image to use 16.04.
 - VirtualBox provider to use centos/7 image + vagrant-vbguest plugin.
 - Improved docs so it is clear that vagrant-vbguest plugin is only
   required with VirtualBox.
 - Clarified comment and made it independent of the release.
 - Refactored the kolla and kolla-ansible paths to be based on the
   username used by Vagrant, that can change depending on the image.

The 's' command wasn't closed properly. This was fixed in kolla repo
before it was decided that the dev env should go in kolla-ansible.

After the repo split into kolla and kolla-ansible the Vagrant
development environment was broken.

With this change Vagrant will run from kolla-ansible and kolla
repo is expected to be in the same directory level so the
bootstrap can include it inside the VM.

 - Modified the bootstrap code to copy both repos into the VM.
 - Added one configuration token to specify kolla-ansible location
   inside the VM.
 - Updated the docs.

The file path was not properly passed to the '-x' test which caused it
to always return true.

This commit simplifies the test for existing command by relying only on
the exit code of `type` rather than checking that the file path is
executable.
