[tempest] Extending tempest for mixed-architecture stacks

Recently I had been running Tempest on my setup testing a
mixed-architecture deployment (x86_64 ans ppc64le compute nodes at the
same time). It seems that some of the migration and affinity tests will
check if there's more than one Compute node before they run. However,
it would seem that's as far as they check, without checking if they are
in fact compatible or even of the same architecture. (my test cluster
is very small, and normally includes two ppc64le Compute nodes, and
sometimes one x86_64 Compute node. Currently one ppc64le machine is
down for repair).
Because the two compute nodes are different architectures, I am getting
failures in various migration and affinity tests, maybe more if I tested
a larger subset. Now granted my particular setup is a special case, but
it does bring to mind some extensions that may be needed for Tempest in
the future. I could see it being possible to have x86_64 and ARM mixed
together in one stack, maybe even tossing in RISC-v someday.
I'm thinking we need to start adding in extra test images, flavors, etc
into the Tempest configurations (as in defining multiple options so that
each architecture can have test images, etc assigned to it, rather than
the current primary and alt image for just one architecture)
Additionally, there should be testcases taking into account the
architectures involved (such as seeing that an instance on one arch
cannot be migrated to the other, as an example). I know this involves a
bit of refactoring, I didn't know if it had even been considered yet.
