Final iteration of improved AAI Cookbook processes needed 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.
