Queue filter support

https://blueprints.launchpad.net/zaqar/+spec/queue-filter-support

Metadata is a group of key-value pairs that belong to a queue. When a queue is created, the user who creates the queue can add the metadata {“keyx”: “valuex”} to distinguish it. It is necessary for zaqar to support the function of queue filter so that Users can select the queue by the specified key-value of metadata. In this blueprints, we will also add queue filter by name.

Problem description

Zaqar doesn’t support queue filter when queue listing, we may add this feature now.

Proposed change

When queue listing, we add filter option in query string parameters like this

GET /v2/queues?key1=value1&key2=value2&name=value3

If metadata of queue and name is consistent with the filter, the queues will be listed to the user, otherwise the queue will be filtered. If filter option is enabled, the metadata of the queue will be returned to user.

API Impact

Lists queues:

GET: /v2/queues?key1=value1&key2=value2

RESPONSE CODE: 200
