Remove webhook server

Now that controller-runtime is able to configure CipherSuites we no
longer need the webhook server. This change remove the custom server but
keeps the pair of functions to map tls versions and cipher suites, it
also bumps controller-runtime to 0.13.1 wich is the minimal that allow
configuring cipher suites.
