Create package index files, for apt and yum

[afbjorklund]

After creating the .deb and .rpm packages,
also create index files for apt and for yum.

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

• Make minikube (and kvm2) installable with "yum" #4716 (yum)

But don't have any signing infrastructure yet:
Need somewhere to store the private gpg keys.

---

Note that the packages for the kvm2 driver are
available separately (PR #4556), to be included.

Once those docker-machine-driver-kvm2packages
are built, they will be included in the indexes too.

[afbjorklund]

Need to make sure that apt-utils and createrepo are available on the build server, before including:

• https://packages.ubuntu.com/apt-utils : /usr/bin/apt-ftparchive

• https://packages.ubuntu.com/createrepo : /usr/bin/createrepo

We probably also need to sign the packages and indexes, before they will actually work for the user...

At this point more of a test, as just generating those indexes locally won't actually do anything.
