    Fix clouds.yaml generation

    Previously the os_tenant_name was being used to generate the
    project_name in clouds.yaml. But if your credentials environment did not
    include an OS_TENANT_NAME declaration but did include an OS_PROJECT_NAME,
    this could result in a bad clouds.yaml and auth failures. This change
    adds the tenant_name in the clouds.yaml as well as setting project_name
    to use os_project_name while still falling back to the previous
    os_tenant_name. Additionally since this is a v2.0/v3 issue, let's
    support properly defining the identity api version if defined.
