proxy: Reuse proxy ports from datapath on restart
 
Previously we only reused the DNS proxy port from the datapath. Change to
reuse the old proxy ports for all proxy redirects from datapath, if
possible. This reduces Listener churn on daemonset Envoy on agent
restart.

With this change the listener update in Envoy logs after agent restart
looks like this:

  begin add/update listener: name=cilium-http-egress:13563 hash=11560876577076369351
  duplicate/locked listener 'cilium-http-egress:13563'. no add/update
  lds: add/update listener 'cilium-http-egress:13563' skipped
