Missed in #5137: Add new models to the homepage

[gsnider2195]

This document should include detailed descriptions of the extras_features decorator options and when to use each of them vs when not to use them.

[gsnider2195]

Another thing that was missed, add a foreign key to the model from ConfigContext if the model would be relevant for making configuration decisions. If so, also update ConfigContextQuerySet, ConfigContextFilterSet, ConfigContext forms, edit and detail views and html templates,

[gsnider2195]

Add model to the global search

[itdependsnetworks]

Updated initial comment and adjusted to be slightly more generic for ease of access.

Would be terrific to also create an additional PR template specifically for use with new-model PRs.
