* Add playbook support

* Update documentation

* Dynamically load collection name where possible (init)

Add support for specifying Ansible hostvars on a platform.

Fix cgroup namespace for docker platform.

Add more recommended configuration to prepare.yml template.

Add more documentation.

Fix the `docker_platform` role so that it works correctly when
more than one platform is specified in molecule.yml.

Move non-provider-specific platform configuration to a `platform` role. This is a breaking change for this version, as functions of `docker_platform` are now provided by platform.

Replace any references to `docker_platform` in playbooks using this collection with `platform`, options stay the same.

Refactor molecule.docker_platform role to handle specifically docker testing containers and not molecule inventory files

Molecule inventory files are now managed by the new molecule.platform role. References to docker_platform in molecule create.yml or destroy.yml files should be updated to use this role in order to work with this version

Add molecule.ec2_platform role, which allows creation and use of ephemeral ec2 instances for test environments.

Update molecule.init role to support deployment of both docker and ec2 platforms. Note that only one platform type is supported per scenario! Also note that there are differences between the Molecule configuration for each platform, so this init role should be used to deploy the appropriate templates!

…le (#9)

Fixes issue primarily affecting CI, where the `init` role fails if it cannot read the collection manifest.
