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.

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.

491aa11e10 Revert "Give kubelet the node-ip value (#5579)"
This reverts commit aa9065749c.

Setting dual-stack node-ip does not work when --cloud-provider is set
to anything, including 'external'. Just set node-ip to the first IP, and
let the cloud provider add the other address.

c0045f415b agent(netpol): Explicitly enable IPv4 when necessary
Before this change, kube-router was always assuming that IPv4 is
enabled, which is not the case in IPv6-only clusters. To enable network
policies in IPv6-only, we need to explicitly let kube-router know when
to disable IPv4.

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.

b6e71ef990 Added support for repeated extra arguments
Problem:
Specifying extra arguments for the API server for example is not supported as
the arguments get stored in a map before being passed to the API server.

Solution:
Updated the GetArgs function to store the arguments in a map that can have
multiple values. Some more logic is added so that repeated extra arguments
retain their order when sorted whilst overall the arguments can still be
sorted for improved readability when logged.

Support has been added for prefixing and suffixing default argument values
by using -= and += when specifying extra arguments.

714979bf6a Ensure that apiserver ready channel checks re-dial every time
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.
