Mazz Mosley 67995ab9e3 Pre-process validation steps
In order to validate a service name that has been specified as an
integer we need to run that as a pre-process validation step
*before* we pass the config to be validated against the schema.

It is not possible to validate it *in* the schema, it causes a
type error. Even though a number is a valid service name, it
must be a cast as a string within the yaml to avoid type error.

Taken this opportunity to move the code design in a direction
towards:

1. pre-process
2. validate
3. construct
