Surya Seetharaman ee461b5bf6 Make nova list and migration-list ignore down cells
This patch makes InstanceLister and MigrationLister ignore down
cells and list the instances/records from the up cell as opposed to
giving 500 to the users as is the current situation.

Listing server and migration records used to give a 500 to users
when a cell database was unreachable. Now only records from available
cells are included to avoid the 500 error. The down cells are basically
skipped when forming the results and this solution is planned to be
further enhanced through the `blueprint handling-down-cell`_.
