Adding flag to skip selinux download

[bjiang27]

Description

There was an issue while installing karavi-authorization-1.4-0.x86_64.rpm, the k3s would fail to install, which is caused by trying to install k3s-selinux unsuccessfully. By adding this flag, the installation would skip the installation of k3s-selinux.

Can we provide the option for customers to override this environment variable in case they want to download the K3s SELinux RPM during the install? For example, INSTALL_K3S_SKIP_SELINUX_RPM=false rpm -i karavi-authorization.rpm

By default we can skip it, but would be good to also allows overriding of this parameter.

We will need to read it in from somewhere during rpm install, the config.json file is probably the only option to enable that from. FYI this download was always disabled, just the flag has changed. We can keep this existing behavior for now and address the override option as a future enhancement.
