Move machine and drivers to minikube repositories

[afbjorklund]

We don't know how long the docker/machine and machine-drivers organization will stay active.

Both docker/machine and boot2docker/boot2docker are deprecated and dead since 2019.

So there is no release for Docker 20.10 and later releases, and eventually they might disappear.

We need to maintain our own fork of the git repos, until it can be integrated more into minikube.

This affect the current repositories:

• github.com/docker/machine -->
  github.com/machine-drivers/machine

• github.com/boot2docker/boot2docker -->
  github.com/machine-drivers/boot2docker

• github.com/dhiltgen/docker-machine-kvm -->
  github.com/machine-drivers/docker-machine-kvm
  github.com/machine-drivers/docker-machine-driver-libvirt

• github.com/machine-drivers/docker-machine-driver-hyperkit

• github.com/docker/machine/drivers/vmwarefusion
  github.com/machine-drivers/docker-machine-driver-vmware

• github.com/Parallels/docker-machine-parallels -->
  github.com/machine-drivers/docker-machine-parallels

See also #9805 about different architectures

We are currently in the process of converting all the drivers to (incompatible) minikube versions.
So far we have done the "kvm" and the "none" drivers, and are about to do the "generic" driver.
We also have patches to the "hyperv" and "hyperkit" drivers, so they are not identical either...
At some point, we need to stop naming the binaries as docker-machine-driver whatsoever.

We should break out the kvm and hyperkit drivers from the "minikube" source code repository,
and set them up with build infrastructure like these other two external (not compiled in) drivers.
Currently they are making the Makefile and other files for minikube needlessly complicated,
since they need to be cross-compiled and add dependencies to native libraries and so on.

See #9583

---

Internal drivers:

• virtualbox
• hyperv
• none (local)
• generic (remote)

External drivers:

• kvm
• hyperkit
• vmware
• parallels

Note that docker and podman are not (real) libmachine drivers.

All minikube driver names are hardcoded into the main binary.

[afbjorklund]

Since we download the drivers ourselves now, users don't actually need to notice much.

We just have to make sure to use the same feature, also for "vmware" and "parallels".

[afbjorklund]

We probably need a separate github organization for this, just for minikube ?

Could also be used to gather some of the personal repositories currently used.

I am okay with moving it to minikube, it would be less complicated release and code review

I'm not sure to fully understand the target.
Is the target to :

• move / duplicate all drivers in the repo
• move / duplicate all drivers in the machine-drivers organization
• move / duplicate all drivers in a new repo or organization

Can you provide an update about this issue ?

The "none" driver has been forked, to the "none" driver.

The "generic" driver has been forked, to the "ssh" driver.
