Add ADR and AF to API

[lbeaufort]

From @vrajmohan:

ADRs and AFs are similar to MURs in may respects:

• they have a similar but simpler data structure
• they are available in the same Postgres DB

This task is to:

• retrieve ADRs and AFs from Postgres
• load any attached documents into S3
• index the ADRs and AFs in Elasticsearch

Most of the design and code for MURs can be reused here.

Developer testing

• Take a backup of dev
• Take a baseline load test of dev
• Add ADR/AF locust tests
• Reload legal docs: cf run-task api "python manage.py initialize_current_legal_docs" -m 4G --name reinit-legal-docs
• Re-load test dev with a manual deploy
• Test front-end legal search on dev with manual deploy
• Make a follow-up ticket for:
  • backing up dev after merge/reload
  • and backing up, reloading legal docs, and backing up again on stage and prod

steps:

1. define how the ADR and AF docs look like: which fields need to be included
2. define doc type mapping file and add them to ./webservices/legal_docs/index_management.py
3. query database, build ADR and AF doc, index it, refer to:
   ./webservices/legal_docs/current_murs.py

it is 'one doc build, one doc injected' indexing approach.
