[kbn-test] use slightly more debug-friendly error output (#21985)
A couple times while debugging failures in `functional_tests(_servers)` with people I've asked for stack traces and received responses like "that's all there is", and it turns out that's right, because the cli's are passing the error object directly to `chalk.red()`, which converts it into a string that only includes the message. This pr moves the common operations from `run_tests/cli.js` and `run_servers/cli.js` into `lib/run_cli` and includes test for the common functionality there, as well as a common error printing logic that still includes the red message, but also includes a stack trace that will help out a lot in debugging.
