Allow to pass cinderv3 internal params

This patch allows to pass number of retries to cinderv3 module
via connection_params.

cinder:
  controller:
    client:
      connection_params:
        connect_retries: 2
        connect_retry_delay: 10
  client:
    connection_params:
      connect_retries: 2
      connect_retry_delay: 10

 * Remove dead code from cinder.client
 * Increase default retries to 60sec
