Copy the general flow and example commands to the API walkthrough, to…

[david-martin]

… be used with a new quickstart script

A few changes here:

• Copy the mgc quickstart script to a new quickstart for trying out the API walkthrough
  • The main thing this gives us is a local environment with mgc running and configured with route53 integration, all from a 1 liner
  • This script can exist along with the new local-setup-api make target as both have different audiences (trying it out vs. local development)
• Copy the general flow of the stitch poc demo script into the api walkthrough doc.
  • Includes numerous TODOs as placeholders
  • Includes example commands copied form the demo script. Some may work, some may need to be tweaked
  • Will have assumptions about certain things the stitch poc setup would have done in the clusters. Hopefully all captured in the TDOOs
• Modify the stitch api dashboards install function to work with either local files or remote files (so the script can be run locally while working on it)

To try this out locally, you can follow the first part of 'Platform Engineer Steps (Part 1)' up until the 'Create a Gateway' section
