batch delete resoures

[gordon chung]

there are potentially millions of different resources that Gnocchi can track. it would be nice to have a way to delete more than one resource at a time. i don't have a recommendation on how to do this. ids? matching query? generic ttl?

Yes， that's good! And I think the matching query with attribute_filter is the better choice. :)

    This patch is used to delete batch of resources

    1. Add a method delete in gnocchi/rest/__init__.py to
       accept an attribute filter to delete matched resources.
    2. Add method delete_resources in gnocchi/indexer/sqlalchemy.py
       to delete related data in db.
    3. Add a new rule in policy.
    4. Add document to descrbe the functions

    The HTTP request for deleting a batch of resources by ids
    is looks like:

        DELETE /v1/resource/<resource_type>
            Content-Type: application/json

                    {"in": {"id":[xx_id,yy_id...]}}.

    The HTTP request for deleting a batch of resources filter
    by resources started_data is looks like:

        DELETE /v1/resource/<resource_type>
            Content-Type: application/json

                    {">=": {"started_data": "2016-08-24"}}

    Or even more complicated for deleing a batch of resources:

        DELETE /v1/resource/<resource_type>
            Content-Type: application/json
                    {
                      "and": [
                         {">=": {"started_data":"2016-08-06"}},
                         {"=":{"id":"xxxx_id"}}
                            ]
                    }

    TODO:
        An corresponding gnocchi client CLI needs to
        be added later.

      --type instance

    +---------+-------+
    | deleted | 0 |
    +---------+-------+
