ff6c233e41 Fix egress selector proxy/bind-address support
Use same kubelet-preferred-address-types setting as RKE2 to improve reliability of the egress selector when using a HTTP proxy. Also, use BindAddressOrLoopback to ensure that the correct supervisor address is used when --bind-address is set.

fb0a342a20 Sanitize filenames for use in configmap keys
If the user points S3 backups at a bucket containing other files, those
file names may not be valid configmap keys.

For example, RKE1 generates backup files with names like
`s3-c-zrjnb-rs-6hxpk_2022-05-05T12:05:15Z.zip`; the semicolons in the
timestamp portion of the name are not allowed for use in configmap keys.

e6009b1edf Introduce servicelb-namespace parameter
This parameter controls which namespace the klipper-lb pods will be create.
It defaults to kube-system so that k3s does not by default create a new
namespace. It can be changed if users wish to isolate the pods and apply
some policy to them.

f4cc1b8788 Move all klipper-lb daemonset to common namespace for PodSecurity
The baseline PodSecurity profile will reject klipper-lb pods from running.
Since klipper-lb pods are put in the same namespace as the Service this
means users can not use PodSecurity baseline profile in combination with
the k3s servicelb.

The solution is to move all klipper-lb pods to a klipper-lb-system where
the security policy of the klipper-lb pods can be different an uniformly
managed.

b550e1183a Remove control-plane egress context and fix agent mode.
The control-plane context handles requests outside the cluster and
should not be sent to the proxy.

In agent mode, we don't watch pods and just direct-dial any request for
a non-node address, which is the original behavior.

Remove objects when removed from manifests (#5560)
* Remove objects when removed from manifests

If a user puts a file in /var/lib/rancher/k3s/server/manifests/ then the
objects contained therein are deployed to the cluster. If the objects
are removed from that file, they are not removed from the cluster.

This change tracks the GVKs in the files and will remove objects when
there are removed from the cluster.
