Added a docker compose file for development

* Added Makefile for quick start and stop
* Modified start-enketo.sh for dev with hardcode secrets, single redis config
* Modified start-postgres.sh to listen postgres14-upgrade even if data directory is absent
* Added instruction in README.md

@@ -28,6 +28,8 @@ In addition to the Backend and the Frontend, Central deploys services:
 * Central relies on [pyxform-http](https://github.com/getodk/pyxform-http) for converting Forms from XLSForm. It generally shouldn't be needed in development but can be run locally.
 * Central relies on [Enketo](https://github.com/enketo/enketo-express) for Web Form functionality. Enketo can be run locally and configured to work with Frontend and Backend in development by following [these instructions](https://github.com/getodk/central-frontend/blob/master/docs/enketo.md).
 
+If you want to work on Central codebase and don't want to setup dependent services like Postgresql, Enketo, etc manually then you can run `make dev`, which will start those services as Docker containers. If you are setting up development environment for the first time, please run `make upgrade-successful` to skip the Postgresql upgrade.
