Implements the controller for the new ProxyGroup CRD, designed for running proxies in a high availability configuration. Each proxy gets its own config and state Secret, and its own tailscale node ID. We are currently mounting all of the config secrets into the container, but will stop mounting them and instead read them directly from the kube API once #13578 is implemented. Updates #13406 Signed-off-by: Tom Proctor <tomhjp@users.noreply.github.com>
