Default Image Architecture Attribute

[Simon Murray]

Analog to https://bugs.launchpad.net/horizon/+bug/1519720

In heterogeneous compute environments an operator may require images to have the architecture attribute set in order to schedule the image onto a hypervisor of the correct architecture. Glance (afaict) doesn't provide a method to enforce this attribute to be supplied.

Change https://review.openstack.org/#/c/242458/ proposes to optionally mutate a creation request to include a default architecture (typically x86_64) which allows correct operation for 99% of cases in the deployment described above. Additionally if you so wish it is also flexible enough to add other attributes e.g. set the disk bus to virtio-scsi etc.

Feel free to debate my choice of tactics but I'm of the opinion that for now it is a good enough solution that allows users to get on with their work without having to rework their provisioning solutions.
