Add default cpu model for AArch64
Unlike x86, AArch64 doesn't have a default model.
Usually when using libvirt driver, set cpu mode to custom, nova
will call libvirt to return the default models. But for aarch64,
the support CPU models varies according to machine type.
AArch64 use "virt" as the default machine type. In Qemu it support
several models, and we should choose "max" as the by default one.

Title:
Cpu model is not correct on Aarch64/Qemu/Custom mode
Status in OpenStack Compute (nova):
Fix Released
Bug description:
Background:
We'd like to setup Nova and Devstack Upstream CI. Should support launch vm
via Qemu virt_type. But host-passthrough mode(default in Aarch64) doesn't work
on Qemu. So we can just use "custom" and specify CPU-model.
But actually Aarch64 don't return available cpu models list from
Libvirt side. Ref:https://libvirt.org/html/libvirt-libvirt-
host.html#virConnectGetCPUModelNames
So we should use the specified ones from config file. And add default
ones to it on Aarch64.
Nova-cpu.conf:
[libvirt]
live_migration_uri = qemu+ssh://stack@%s/system
cpu_mode = custom
virt_type = qemu
cpu_model = cortex-a57
