Brad Davidson ff679fb3ab Refactor supervisor listener startup and add metrics 
* Refactor agent supervisor listener startup and authn/authz to use upstream
  auth delegators to perform for SubjectAccessReview for access to
  metrics.
* Convert spegel and pprof handlers over to new structure.
* Promote bind-address to agent flag to allow setting supervisor bind
  address for both agent and server.
* Promote enable-pprof to agent flag to allow profiling agents. Access
  to the pprof endpoint now requires client cert auth, similar to the
  spegel registry api endpoint.
* Add prometheus metrics handler.

Michal Rostecki 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.

Michal Rostecki c707948adf netpol: Add dual-stack support 
This change allows to define two cluster CIDRs for compatibility with
Kubernetes dual-stuck, with an assumption that two CIDRs are usually
IPv4 and IPv6.

It does that by levearaging changes in out kube-router fork, with the
following downstream release:

Michal Rostecki 4fed9f4052 netpol: Use kube-router as a library 
Before this change, we were copying a part of kube-router code to
pkg/agent/netpol directory with modifications, from which the biggest
one was consumption of k3s node config instead of kube-router config.

However, that approach made it hard to follow new upstream versions.
It's possible to use kube-router as a library, so it seems like a better
way to do that.

Instead of modifying kube-router network policy controller to comsume
k3s configuration, this change just converts k3s node config into
kube-router config. All the functionality of kube-router except netpol
is still disabled.
