Docker image to make running Nitro Porter easier

[rsnyman]

A Docker image is a great way to package an application like Nitro Porter, enabling someone to just download the Docker image and run a container (be it for the web or for the CLI).

That's an excellent idea, thanks.

My biggest concern about this is that I primarily work on a Mac, and my understanding is that Docker for Mac continues to suffer from performance issues, especially around database handling. Because Porter is database-intensive, my concern is I'm going to get this all setup and it'll be mostly useless for Mac-based engineers doing large migrations due to that. Running Porter on an M1 natively is incredibly fast and I'd hate to lose that gain.

[rsnyman]

Yeah, I use Linux, I don't know much about Docker on Mac.

The next release will include Docker support.
