eCR Viewer setup script + variable pattern setting 🖌️

[alismx]

Changes Proposed

• New vars, dibbs_service and dibbs_version to enable selecting a dibbs project during builds.
• The addition of new .gitignore
• adds *.env file loads in the ~/.bashrc file which sets vars across reboots
• GitHub workflow packMachines.yml, to create Docker images dynamically based on provided service and version inputs.
• Modification of the docker-compose.yml to remove hardcoded image versions and allow the version to be set as an environment variable at build time.
• Setup wizard to help users set up the eCR Viewer application using Docker Compose.
• A new build.sh script is also included in utils/ for executing the Packer build with the required service and version variables.

Additional Information

• The setup wizard is specific to ecr-viewer. We could parameterize it, but I think that might be more work than just writing one specific to query-connector.

Testing

Reviewers can verify these changes by:

• Run the following command in the utils directory:
  • ./build.sh dibbs-ecr-viewer v2.0.0-beta
• Check Docker containers are properly setup
• Verify wizard script, sudo ./wizard.sh
• Run packer builds
• Poke it
• Prod it

I converted back to draft because the environment variables did not stay set in the ways I expected. I'll reopen this for review shortly.
