Brad Davidson ffe72eecc4 Address issues with etcd snapshots
* 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.

Brad Davidson 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.

Fix issue with datastore corruption on cluster-reset (#5515)
* Bump etcd to v3.5.4-k3s1
* Fix issue with datastore corruption on cluster-reset
* Disable unnecessary components during cluster reset

Disable control-plane components and the tunnel setup during
cluster-reset, even when not doing a restore. This reduces the amount of
log clutter during cluster reset/restore, making any errors encountered
more obvious.

Brad Davidson f37e7565b8 Move the apiserver addresses controller into the etcd package
This controller only needs to run when using managed etcd, so move it in
with the rest of the etcd stuff. This change also modifies the
controller to only watch the Kubernetes service endpoint, instead of
watching all endpoints in the entire cluster.

Fixes an error message revealed by use of a newer grpc client in
Kubernetes 1.24, which logs an error when the Put to etcd failed because
kine doesn't support the etcd Put operation. The controller shouldn't
have been running without etcd in the first place.

Fix URL pruning when joining an etcd member (#3832)
* Fix URL pruning when joining an etcd member

Problem:
Existing member clientURLs were checked if they contain the joining
node's IP. In some edge cases this would prune valid URLs when the
joining IP is a substring match of the only existing member's IP.
Because of this, it was impossible to e.g. join 10.0.0.2 to an existing
node that has an IP of 10.0.0.2X or 10.0.0.2XX:

level=fatal msg="starting kubernetes: preparing server: start managed database:
joining etcd cluster: etcdclient: no available endpoints"

Solution:
Fixed by properly parsing the URLs and comparing the IPs for equality
instead of substring match.

Brad Davidson c0d129003b Handle loadbalancer port in TIME_WAIT
If the port wanted by the client load balancer is in TIME_WAIT, startup
will fail. Set SO_REUSEPORT so that it can be listened on again
immediately.

The configurable Listen call wants a context, so plumb that through as
well.

Always use static ports for client load-balancers (#3026)
* Always use static ports for the load-balancers

This fixes an issue where RKE2 kube-proxy daemonset pods were failing to
communicate with the apiserver when RKE2 was restarted because the
load-balancer used a different port every time it started up.

This also changes the apiserver load-balancer port to be 1 below the
supervisor port instead of 1 above it. This makes the apiserver port
consistent at 6443 across servers and agents on RKE2.

Additional fixes below were required to successfully test and use this change
on etcd-only nodes.

* Actually add lb-server-port flag to CLI
* Fix nil pointer when starting server with --disable-etcd but no --server
* Don't try to use full URI as initial load-balancer endpoint
* Fix etcd load-balancer pool updates
* Update dynamiclistener to fix cert updates on etcd-only nodes
* Handle recursive initial server URL in load balancer
* Don't run the deploy controller on etcd-only nodes
