Bug Type:         Feature/Change Request
Bug description:FPM Status should use a reserved worker

Description:
------------
PHP-FPM should have a reserved worker available to serve the status page
even if all other workers are busy.

This prevents false alarms when monitoring the status page (and it being
unable to be served due to worker exhaustion)

The thought on this comes from MySQL - where you can hit max connections
but there is a reserved connection so a superuser can connect and still
work with the server.

Test script:
---------------
Exceed the configured worker count.
Attempt to access the status page.

Expected result:
----------------
I would expect to see the status page.

Actual result:
--------------
Attempt to access the status page will fail.
