We should be reading from the hijacked bufio.ReaderWriter instead of
directly from the net.Conn. There is a race condition where the
underlying http handler may consume bytes from the hijacked request
stream, if it comes in the same packet as the CONNECT header. These
bytes are left in the buffered reader, which we were not using. This was
causing us to occasionally drop a few bytes from the start of the
tunneled connection's client data stream.

If CCM and ServiceLB are both disabled, don't run the cloud-controller-manager at all;
this should provide the same CLI flag behavior as previous releases, and not create
problems when users disable the CCM but still want ServiceLB.

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.

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.

Watching pods appears to be the most reliable way to ensure that the
proxy routes and authorizes connections.

This is required to make the websocket tunnel server functional on
etcd-only nodes, and will save some code on the RKE2 side once pulled
through.

Closing idle connections isn't guaranteed to close out a pooled connection to a
loadbalancer endpoint that has been removed. Instead, ensure that requests used
to wait for the apiserver to become ready aren't reused.

Several types contained redundant references to ControlRuntime data. Switch to consistently accessing this via config.Runtime instead.

Since we now start the server's agent sooner and in the background, we
may need to wait longer than 30 seconds for the apiserver to become
ready on downstream projects such as RKE2.
Since this essentially just serves as an analogue for the server's
apiReady channel, there's little danger in setting it to something
relatively high.
