Ansible roles and group of roles that constitute the deploy stack.

All environments require the following variable to be set by CI or at the terminal command:

• _env_type - the type of environment, e.g. development, production, etc.

You must pass the following additional variables into an Ansible play before running it with ce-provision if you intend to use the AWS subset of roles:

• _aws_profile - the Boto3 profile to use
• _aws_region - the AWS region to act in
• _aws_resource_name - the name of the variables directory, which will match the Ansible host group created by the AWS discovery plugin

Please also read carefully the AWS README file at docs/roles/AWS.md.
