Create configuration wizard that allows STLTs to configure environment variables on first run - Query Connector

[rin-skylight]

We will need to create a shell script that gets copied into the machine, which allows an IT admin to dynamically configure the environment variables for all images in the Docker Compose stack. This will include database strings, cloud storage account strings, etc.

Acceptance Criteria:

• Script checks for existing .env file and backs it up. (Make sure that you support multiple .bak files - consider naming backups with date/time stamp)
• Script prompts for all needed variables for the Query Connector
• .env file is properly created
• Script brings down and restarts the docker stack with the proper docker compose command.
