This makes the instance_list module support batching across cells with a couple of different strategies, and with room to add more in the future. Before this change, an instance list with limit 1000 to a deployment with 10 cells would generate a query to each cell database with the same limit. Thus, that API request could end up processing up to 10,000 instance records despite only returning 1000 to the user (because of the limit). This uses the batch functionality in the base code added in Iaa4759822e70b39bd735104d03d4deec988d35a1 by providing a couple of strategies by which the batch size per cell can be determined. These should provide a lot of gain in the short term, and we can extend them with other strategies as we identify some with additional benefits.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
