Make user roles explicit

[dwelsch-esi]

In the introduction or new user documentation, explicitly state the intended user roles (personas) for KEDA. There might only be one role (Operator).

A second implicit user role always exists (project Contributor); be careful to keep Contributor documentation separate from the Operator documentation.

If there is more than one user role (ignoring Contributor), write procedures for each persona into separate Guide documents.

Use-Case

The distinction between user roles is based on what the user needs to do with the product. KEDA seems to have only one explicit user role (or persona), an Operator using KEDA to scale resources on a Kubernetes installation. Regardless, this user role should be explicitly distinguished from the project Contributor user role. Use cases are different between the two roles.

Specification

The definition of the Operator role could be as minimal as a "who should use this documentation" paragraph in the product introduction.

One strategy for separating the documentation is to confine the Contributor docs to the GitHub repo.
