Subject: [PATCH] mcp: salt-formulas: armband: Extend libvirt_domain

Add new state in armband salt formula that extends salt's virt
libvirt_domain.jinja template with support for:
- hw_firmware_type;
- virt_machine_model;
- cpu_model;

These will later be leveraged via salt virt formula with AArch64
specific values.

+Subject: [PATCH] libvirt_domain.jinja: Add AArch64 support
+
+Salt virt state relies on a Jinja template to create a libvirt
+XML definition for each new VM.
+This template needs to be extended with a few specific options
+for AArch64:
+- UEFI loader support (pflash);
+- custom machine model (e.g. 'virt-2.9'), since AArch64 defaults to
+  'integratorcp';
+- custom cpu model;
+
+Allow all these to be parametrized from the salt virt formula,
+which we will also adapt to allow the params to be passed via our
+reclass model.
