PR updates
* README.md + update list of modern instance types + add caveat regarding linux-vanilla vs. linux-virt * alpine-ami.yaml + build instance type is always t3.nano + block device where we build is always /dev/xvdf + add optional AMI encryption + always enable AMI SR-IOV flag (vanilla & virt both have the necessary driver) + no need to pass volume_name to make_ami.sh * make_ami.sh + replace hard tabs with 4 spaces + always set up edge repositories + no need to add mkinitfs package, it's a dependency of linux-* + fix update of /etc/inittab + fix configuration of NTP + declare local vars in main() + device is always /dev/xvdf * variables.json-default/example + improve comment for kernel_flavor + default add_repos is now empty + remove acct & e2fsprogs-extra from add_pkgs + add optional AMI encryption + remove sriov_enable, build_instance_type, and volume_name vars
