df10b51c91 [systemd] Add value to LimitNOFILE due to performance problems 
When k3s is installed on an OS with default high ulimits, performance
issues can be observed. This was discovered on CoreOS where the default
value is 1073741816. Symptoms include very slow file operations such
as installing a Rook/Ceph cluster will take ~6 hours instead of ~10 minutes.

A google search for 'container LimitNOFILE' will show that most major
projects set this already, including the (unused) containerd systemd unit
found in this repository at /vendor/github.com/containerd/containerd/containerd.service

k3OS is not affected becuasse the default there is already 1048576.

See description in coreos/fedora-coreos-tracker#329

7f68b7f3cd contrib/ansible: Use kubectl to set the server url in conf 
Sometimes https://127.0.0.1:6443 can be written in the conf, the regexp does
not account for that.

6655ecbcef Fix an inconsistency in contrib/ansible/README.md 
The example inventory uses the group `kube-cluster`, but the playbooks references `k3s-cluster`. This resolves the inconsistency.
