"""
Module for handling openstack keystone calls.

:optdepends:    - keystoneclient Python adapter
:configuration: This module is not usable until the following are specified
    either in a pillar or in the minion's config file:

    .. code-block:: yaml

        keystone.user: admin
        keystone.password: verybadpass
        keystone.tenant: admin
        keystone.tenant_id: f80919baedab48ec8931f200c65a50df
        keystone.auth_url: 'http://127.0.0.1:5000/v2.0/'
        keystone.verify_ssl: True

    OR (for token based authentication)

    .. code-block:: yaml

        keystone.token: 'ADMIN'
        keystone.endpoint: 'http://127.0.0.1:35357/v2.0'

    If configuration for multiple openstack accounts is required, they can be
    set up as different configuration profiles. For example:

    .. code-block:: yaml

        openstack1:
          keystone.user: admin
          keystone.password: verybadpass
          keystone.tenant: admin
          keystone.tenant_id: f80919baedab48ec8931f200c65a50df
          keystone.auth_url: 'http://127.0.0.1:5000/v2.0/'
          keystone.verify_ssl: True

        openstack2:
          keystone.user: admin
          keystone.password: verybadpass
          keystone.tenant: admin
          keystone.tenant_id: f80919baedab48ec8931f200c65a50df
          keystone.auth_url: 'http://127.0.0.2:5000/v2.0/'
          keystone.verify_ssl: True

    With this configuration in place, any of the keystone functions can make use
    of a configuration profile by declaring it explicitly.
    For example:

    .. code-block:: bash

        salt '*' keystone.tenant_list profile=openstack1
