Index Category data for search

[nateiam]

As Herd Product Owner I want to build a searchable index of Category data

This story relies on existing indexed search infrastructure but includes all development work to index Category data and make this index available to Herd searches.

Acceptance Criteria

• Index exists that contains the following for all Categories in Herd:
  • Category and searchable attributes (key (not searchable), display name, description)
  • Child Categories and their searchable attributes
  • Index contents are validated in a similar fashion to BDef index
• Index build can be triggered and managed by existing endpoint, see #285
• Index is integrated with existing indexed search infrastructure - index is available near-immediately after new infrastructure deployment (fully automated)
