Amphora image requires explicit --property hw_architecture='x86_64 in multi-arch clouds

[Nir Magnezi]

Initially reported here: https://bugzilla.redhat.com/show_bug.cgi?id=1677064

Description of problem:
In our multi-architecture cloud, creating a load balancer occasionally fails because it's being spun up on ppc64le compute nodes (the octavia-amphora image is x86_64 only).

Version-Release number of selected component (if applicable):
octavia-amphora-13.0-20190109.1.x86_64

How reproducible:
If no hw_architecture property is specific and the image attempts to be deployed onto ppc64le nodes, it will fail.

Steps to Reproduce:
1. Leave out hw_architecture='86_64' property from the image
2. Try to deploy image. If it tries to schedule on a ppc64le node it will fail
3.

Actual results:
Failure without explicit hw_architecture

Expected results:
If this can only be created on x86_64 nodes, can we default to x86_64 for this image?

Additional info:
If it's not possible to default to x86_64, we can move this to a Docs issue and we can update the documentation to inform customers they need to set this property for the image.

    Specify Octavia amphora image hw_architecture property in Glance

    In the case of a multi-architecture cloud, Nova will try to schedule an
    Amphora to a non-x86_64 architecture compute node, which will fail the
    load balancer creation in Octavia.

    This patch explicitly specifies the Amphora image hw_architecture
    property when the image is being uploaded to Glance. By doing so, it
    hints the Nova scheduler which compute nodes to take into
    account when it schedules an Amphora instance.

    The default for hw_architecture is x86_64, which resembles the current
    behavior since this is the only image type that we ship.

    Closes-Bug: #1818563
