Add rust and cargo as dependencies

Add license

Don't allocate terminal

Test Docker image by invoking application with "--help" and "test-filters -v"

Add type hints

Refactor indexing of filters by kind into separate method

List environment variables for SMTP handler

Update readme with notes on deploying via Helm

Adjust deployment to the new version of Kubewatcher

Grant permission to node resources
