Can't create claim without passing optional parameters

[Fernando Ribeiro]

Unlike the API or the WebSocket endpoints, the Python client requires passing the optional 'ttl' and 'grace' parameters due to a validation error in Zaqar.

* Source Code *

from zaqarclient.queues.v1 import client

client = client.Client('http://localhost:8888', conf={'auth_opts':{'options':{'client_uuid':...,'os_auth_token':...,'os_auth_url':'http://localhost:5000/v3.0/','os_project_id':...}}}, version=1.1)

queue = client.queue('SampleQueue')

claim = queue.claim()

for msg in claim
  print msg

* Stack trace for missing 'ttl' parameter *

Please advise if the bug should be first reported against the Python client instead.
