Add pre-{install,purge} support for base image
Extend <lib.sh> and its invocation from <ci.deploy.sh> with support for modifying foundation node VMs base image prior to using it with: - additional APT GPG keys; - additional APT repos; - packages to pre-install; - packages to pre-remove; - (non-configurable) cloud init datasource via NoCloud only, so VCP VMs won't wait for metadata service; While at it, re-use the resulting image as a base for another round of pre-patching (same operations as above are supported) to provide a base image for VCP VMs. Add AArch64-specific configuration based on new mechanisms: - pre-install linux-image-generic-hwe-16.04-edge (and headers) for foundation node and VCP (common) image (also requires new repo and its key); - pre-install cloud-init for VCP image (it should already be installed, but script needs non-empty config for VCP to create the VCP image and transfer it over to Salt Master); NOTE: cloud-init is required on VCP VMs for DHCP on 1st iface.
