* Support for disabling UEFI in inspector
* Authtoken signing_dir argument
* ironic::drivers::deploy manifest
* ironic::db::inspector_sync manifest
* enabled_drivers and rabbit_user from init manifest
This change leaves out the following deprecation
* Implicit including of ironic::pxe in inspector (due to unclear CI problems)
* Other rabbit_* parameters (THT still uses them, sigh)
