Print warning when running one-worker cluster (#2565) 
* Print warning when running one-worker cluster

Running Puma in cluster-mode is likely a misconfiguration in most
scenarios.

Cluster mode has some overhead of running an addtional 'control' process
in order to manage the cluster. If only running a single worker it is
likely not worth paying that overhead vs running in single mode with
additional threads instead.

There are some scenarios where running cluster mode with a single worker
may still be warranted and valid under certain deployment scenarios, see
the linked issue for details.

From experience at work, we were able to migrate our Rails applications
from single worker cluster to single-mode and saw a reduction of RAM
usage of around ~15%.

Closes #2534

* Remove link to issue

* Add #silence_single_worker_warning option

* Test single_worker_warning
