Having separate tokens for server and agent nodes is a nice feature.
However, passing server's plain `K3S_AGENT_TOKEN` value
to `k3s agent --token` without CA hash is insecure when CA is
self-signed, and k3s warns about it in the logs:
```
Cluster CA certificate is not trusted by the host CA bundle, but the token does not include a CA hash.
Use the full token from the server's node-token file to enable Cluster CA validation.
```
Okay so I need CA hash but where should I get it?
This commit attempts to fix this issue by saving agent token value to
`agent-token` file with CA hash appended.

* Use INVOCATION_ID to detect execution under systemd, since as of a9b5a1933f NOTIFY_SOCKET is now cleared by the server code.
* Set the unit type to notify by default for both server and agent, which is what Rancher-managed installs have done for a while.

* Increase the default snapshot timeout. The timeout is not currently
configurable from Rancher, and larger clusters are frequently seeing
uploads fail at 30 seconds.
* Enable compression for scheduled snapshots if enabled on the
command-line. The CLI flag was not being passed into the etcd config.
* Only set the S3 content-type to application/zip if the file is zipped.
* Don't run more than one snapshot at once, to prevent misconfigured
etcd snapshot cron schedules from stacking up.

87e1806697 removed the OwnerReferences
field from the DaemonSet, which makes sense since the Service may now be
in a different namespace than the DaemonSet and cross-namespace owner
references are not supported. Unfortunately, we were relying on
garbage collection to delete the DameonSet, so this started leaving
orphaned DaemonSets when Services were deleted.
We don't want to add an a Service OnRemove handler, since this will add
finalizers to all Services, not just LoadBalancers services, causing
conformance tests to fail. Instead, manage our own finalizers, and
restore the DaemonSet removal Event that was removed by the same commit.

Since #4438 removed 2-way sync and treats any changed+newer files on disk as an error, we no longer need to determine if files are newer on disk/db or if there is a conflicting mix of both. Any changed+newer file is an error, unless we're doing a cluster reset in which case everything is unconditionally replaced.

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.

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.

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.
