Updating README and local config

[sethstoudenmier]

Description: Update the README and other aspects of the usaspending-api codebase to support local development.

Technical details: Below is a brief list of changes going file by file in order to give a high-level reasoning of "why".

• .env.template
  • The wrong database name was used for the Broker DB
• .gitignore
  • Support change of the docker-compose.yaml to use more relative paths
• Dockerfile
  • The es_configure job relies on curl to query the ES indexes
  • Without curl the elasticsearch_indexer job fails to create the templates for the ES indexes and thus creates many mis-typed fields on the indexes
• Dockerfile.spark
  • Similar changes that were made to the Dockerfile to change the base image used
  • Also had to update the version of OpenJDK
  • Some new installs were needed to support the different image
  • Old installs were left in place to avoid breaking things
• Dockerfile.testing
  • Update to the OpenJDK version similar to Dockerfile.spark
  • Remove the logic that changed the working directory in favor of having the volume named /usaspending-api instead of /dockermount
• Makefile
  • Update references of docker-compose to instead use docker compose (read more here)
  • Some paths updated to relative paths
• README.md
  • Some cleanup
  • Made changes to reflect the steps that I took when setting everything up
• docker-compose.yaml
  • Removed the version as that is deprecated
  • Updated to use relative paths; main reasoning here is to avoid use of parameters such as $PWD in windows and also more WSL friendly
  • Updated the usaspending-test volume to be /usaspending-api in the container to support hot reload when testing
• usaspending_api/search/tests/integration/test_spending_by_category_categories.py
  • This test never mocked the ES Transaction index; as a result if you tried to run this locally and you had data on your ES index it would fail because it would retrieve data
  • Would be good to update the test cases to return actual data instead of a count of zero, but that is out of the scope of this PR

Requirements for PR merge:

1. [x] Unit & integration tests updated
2. [x] API documentation updated
3. [x] Necessary PR reviewers:
   • [x] Backend
4. [x] Matview impact assessment completed
5. [x] Frontend impact assessment completed
6. [x] Data validation completed
7. N/A Appropriate Operations ticket(s) created
8. N/A Jira Ticket

Area for explaining above N/A when needed:

@sethstoudenmier What do you think about adding an init.sql script to run some common SQL commands when setting up the DB for the first time, since we're updating the docs? There are some common issues and their solutions don't seem to be documented publicly.

• ALTER USER usaspending SET SEARCH_PATH TO "public", "raw", "int", "temp", "rpt";
  • This prevents a common error about tables outside of the public schema not being found.
• Create the etl_user
  • This user is needed for migrations to run.
• Create the readonly user
  • This user is needed for migrations to run

Funny you should say that, I actually had that in place originally. The problem is that it conflicts with the Travis CI/CD build process when we use the --reuse-db flag because it attempts to create users that already exist. Instead I opted to document that in the README.

Ahh.. that makes sense with the CI/CD process. I missed the changes to the README, because it was collapsed. I'm happy with those steps being documented!
