Make minikube (and kvm2) installable with "yum"

[afbjorklund]

When we do the apt indexing of the .deb packages*,
we might as well do the yum indexing of the .rpm.

• See Make minikube (and kvm2) installable with "apt" #3110

This should include both minikube and the kvm2 driver...
That is, the new docker-machine-driver-kvm2 package*.

• See Debian package should include the kvm driver (docker-machine-driver-kvm2) #2982

Basically, provide something similar to what kubectl has:

• https://packages.cloud.google.com/apt/ (xenial)

• https://packages.cloud.google.com/yum/ (el7)

This includes signing the packages with a GPG key.

Not sure if we can use the Google Cloud Packages ?

• https://packages.cloud.google.com/apt/doc/apt-key.gpg

• https://packages.cloud.google.com/yum/doc/yum-key.gpg

still waiting on #4716 (comment)

[medyagh]

we still like to do this, but it seems like we are blocked by some issues, if anyone can help to make this happen we need hep !

[afbjorklund]

We will need to do either of: 1) run rpm forever (close this ticket) 2) host yum repository ourselves (sig release won't help us)
