Optimise the workers used for all services for the AIO

Browse Source 
The current default number of worker threads for the AIO consumes too many
resources, resulting in gate check failures.

This patch implements a set of sane defaults for the AIO, reducing the
number of workers for most services to 2.

Implements: blueprint gate-split
