fix: allow DNS disconnection events to happen in k8s (#19145)

Browse Source 
in k8s things really do come online very asynchronously,
we need to use implementation that allows this randomness.

To facilitate this move WriteAll() as part of the
websocket layer instead.

Bonus: avoid instances of dnscache usage on k8s
