Matt Riedemann 9b3c4736a3 Allow None for block_device_mapping_v2.boot_index ... The legacy v2 API allowed None for the boot_index [1]. It allowed this implicitly because the API code would convert the block_device_mapping_v2 dict from the request into a BlockDeviceMapping object, which has a boot_index field that is nullable (allows None). The API reference documentation [2] also says: "To disable a device from booting, set the boot index to a negative value or use the default boot index value, which is None." It appears that with the move to v2.1 and request schema validation, the boot_index schema was erroneously set to not allow None for a value, which is not backward compatible with the v2 API behavior. This change fixes the schema to allow boot_index=None again and adds a test to show it working. This should not require a microversion bump since it's fixing a regression in the v2.1 API which worked in the v2 API and is already handled throughout Nova's block device code.
