Rebuild multiple nodes at once

Rebuild multiple nodes in a simulation at once. Rebuilding a node means returning the node to either the state of the current checkpoint of its simulation or its initial, first boot state. When rebuilding from the initial state, all repeatable instructions for selected nodes will be applied. All existing instructions created for the selected nodes which have not yet been completed will be failed. All existing instructions created for the selected nodes which have not yet been delivered will be cancelled. All nodes must be part of the same simulation in the `ACTIVE` state. **Required scope:** `air:simulation_edit` (roles: `air_org_admin`, `air_user`)
