Create Administrator Persona for Knative

## What is changing? (Please include as many details as possible.)

We want to create a administrator persona, complete with persona name, attributes, wants, needs and pains.

## Context

The DUX WG has expressed interest in separating the documentation by persona, this would be a step in achieving that outcome.

## How will this impact Knative users?

Users will more easily be able to find topics relevant to their persona as a administrator, and not be bogged down with the complexity of other persona's needs

## Prototype

N / A

## Potential Feature List

N / A

No files, tests, or entry points are named. Start by reviewing the requested administrator persona attributes, wants, needs, and pains with the DUX WG context; done means a persona artifact that supports separating documentation for administrators from other personas.
