12235fe733 Perform basic validation on K3S_URL in install.sh 
This allows us to fail quickly if we're handed a schemeless or plain
HTTP URI, rather than having the agent barf when the systemd unit
starts. For an operator, this makes for a cleaner error up front and
clear messaging for how to fix the situation.

921e11930e Always keep restarting k3s process by openrc 
When for some reason, k3s crashes, and can't startup again, e.g. when
the data backend is not available (dqlite crashed, database server is
offline, ...), on openrc systems, supervise-daemon will try to restart
it, as per supervise-daemon(8):

    respawn-max:

    Sets the maximum number of times a daemon will be respawned during
    a respawn period. If a daemon dies more than this number of times
    during a respawn period, will give up trying to respawn it and exit.
    The default is 10, and 0 means unlimited.

Setting respawn-max to 0, makes sure a k3s process on openrc systems will
keep trying to come online, even if the database backend is offline for a
longer period of time.

This aligns the openrc service configuration with the systemd
configuration, which has

    Restart=always
    RestartSec=5s

b4335630b7 [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

If you are installing k3s on a selinux enforcing system then we
required that you also install k3s_selinux RPM to put in the proper
policy.

2fe5d2768b Changed SELinux error to fatal 
If the install errors out on semanage not found, a file not found is
thrown as a 'file not found' for error. Updating to 'fatal' resolves
this as the script then exits as intended and throws an 'error'.
