MINOR: proxy: stress CLI commands with backends/servers loop

Update handlers for "show backend" and "show servers state/conn" so that
stress mode can be used to force the task yielding each time a new
instance is dumped.

This is useful for debugging commands safety with backend/server
deletion in parallel.
