This adds `sesdev create k3s`, which by default will deploy a
master with four workers on openSUSE Tumbleweed.  It will also
deploy on SLE 15 SP3 if you specify `--os=sles-15-sp3`.

k3s is installed by running `curl https://get.k3s.io`.  Helm
is also installed on the master, again using `curl`.  If you
don't want the latest stable k3s, you can install a specific
version with the `--k3s-version` option.  If you want more or
less workers, use `--roles='[master],[worker],[...]`.

This adds the `--deploy-ses` option to `sesdev create k3s`,
which will pull registry.suse.com/ses/7.1/charts/rook-ceph,
then deploy Rook, which in turn will deploy Ceph, and have
it eat all the disks on all the workers.

When deploying on SLE 15, openssl is already installed as
it's a dependency of ca-certificates.  This is not true on
Tumblweed though, so let's just always install it.

This avoids causing confusion by overloading the caasp_deploy_ses setting.
