Make cpu starvation warning's logging destination configurable

[manuelcueto]

As mentioned here This warning log logs directly to System.err, which might be undesirable if the application leverages some custom Logging (i.e Logback, log4cats). the CpuStarvationCheck should contain a configurable Console(most likely through IORuntimeConfig) .

Working on it :). However at a first glance, a Console is too big an abstraction for this functionality. It probably is out of scope, but Something like trait Console extends ConsoleReader with ConsoleWriter would make sense, and then CpuStarvationCheck should only need a ConsoleWriter in reality
