def get_placeholder_conf(setting, placeholder, template=None, default=None):
    Returns the placeholder configuration for a given setting. The key would for
    example be 'plugins'  or 'name'.
    If a template is given, it will try
    CMS_PLACEHOLDER_CONF['template placeholder'] and
    CMS_PLACEHOLDER_CONF['placeholder'], if no template is given only the latter
    is checked.
