This is a stop-gap to prevent accidental push of kernel
images to hub until we sort out doing this from CI.

This lets us boot on packet.net machines and successfully gives
a DHCP lease when installed via iPXE. See #1245

This requires switching to the dosfstools from alpine:edge since neither the
busybox nor alpine:3.5 dosfstools supports the -C option (in fact alpine:3.5
only has mkfs.fat and not mkfs.vfat).
The 511k slack seems like a lot to me, but 256k was somehow not enough.
Fixes#1304.

- the image upload uses the cloud API
- currently auth and image creation need the `gcloud` CLI tool.

A given image is pushed to hub twice, once as
kernel:<kernel version>.<major version>.x and once as
kernel:<kernel version>.<major version>.<minor version>-<n>.
The latter is used to decide if a new kernel image is pushed to hub.
Most users should use the former to pick up the latest kernel.

LTP is compiled in on debian container and the binaries
then copied into another container, which is pushed to hub.
LTP does not compile on Alpine as it uses glibc specific
pthread extensions.
I tried to link LTP statically to not require a glibc based
base image but that failed too.

Passing accel=kvm:tcg causes it to try KVM first if available with a fallback
to TCG (emulated/JIT mode) if it is not available. With this the boot logs gain:
+Hypervisor detected: KVM
and also
-Booting paravirtualized kernel on bare hardware
+Booting paravirtualized kernel on KVM
Among various other noise.
If I rename my host /dev/kvm then this is reversed, although with the following
message:
Could not access KVM kernel module: No such file or directory
failed to initialize KVM: No such file or directory
Back to tcg accelerator.
Q35 is a more modern emulated platform based on the ICH9 host chipset rather
than the default "pc" I440FX (Pentium Pro / Pentium II era) emulation. See
http://wiki.qemu-project.org/Features/Q35 for more info. Switching to Q35 is
not a requirement for enabling KVM but seemed like a reasonable change.

- Currently only works if you add your ssh key in the example yaml, but will replace
with metadata support shortly.
- sshd logging not yet configured (needs to share syslog socket).

- these were set via the Alpine config file previously.
- removed `kernel.panic` as we have decided to avoid reboot on panic.
