AAI Cookbook Improvements - processes are ready for v0.1

In order to support uptake of AAI processes in 0.1, required documentation needs to be produced and made available.

SRCNet0.1 users (operations/development team members in this case, rather than science users) should be able to easily gain an understanding of how to make and use groups.

AC1: AAI documentation required for 0.1 has been and gathered & linked in the cookbook.

AC2: Documentation is user-friendly - so easy to understand with sufficient troubleshooting information when things go wrong. As reviewed by at least one person outside of the Purple team.

AC3: At least one test user has made a group by following the cookbook recipe.

AC4: (If not covered in PI22) A demo has been held, which provides an overview of the SKA-IAM, its workflows, and how this maps to the planned AAI architecture, and how to use IAM in SRCNet0.1

Cut off: limit improvements to 1 FP of effort. This feature is about improving / verifying documentation, not writing a lot of new stuff unless motivated by a reviewer / test user.

Existing Cookbook: https://confluence.skatelescope.org/display/SRCSC/AAI+Docs%3A+AAI+cookbook

Don't have confirmation for AC3

From this point forwards the cookbook will be migrated to the read the docs documentation tree (see https://jira.skatelescope.org/browse/SP-4318 and https://jira.skatelescope.org/browse/SP-4617)

Moving this feature to releasing to close out this piece of work and instead plan work to contribute to those other features moving forward.
