Snap package broken on arm64

[Shawn Horvatic]

It is impossible on a Pi 4 to run: microstack init --auto --compute --join

snap did not link microstack

It also affects macOS version when the computer is on Apple Silicon instead of Intel, but works fine on x86 server.

So, it means that the docs on https://ubuntu.com/openstack/install are correct, and it strictly requires x86 machine and does NOT work on arm64. For some bizarre reason, the snap source code was set up to be installable on arm64...

It looks like on arm64 the latest snap version is 199, while on amd64 it's 245, so that may be the reason why `microstack` command is missing. But the rest of the tools and setup looks OK - pretty much everything except anything related to nova-compute.

It either needs a newer version for arm64 or the snap package has to be updated to drop arm64, which, thanks to Apple, is a pretty popular architecture for workstations now and fully supported by Multipass that's advertised as the simplest way to get MicroStack on a laptop.
