Add docker support

[opis-mark]

Description

Add docker files to eliminate the installation and dependency requirements to have a working environment for tokendito.

Motivation and Context

I use containers for all of my python applications to avoid managing multiple python versions, dependencies, and virtual environments.

How Has This Been Tested?

I tested building and running the application with expected results.

@sevignyj - If I'm reading the error correctly, the linting is upset about 3 files that I didn't change in this branch but yet the build succeeds in main which it is based on. Can you provide any insight?

It looks like the code coverage report is showing a decrease in coverage on files that were not modified by this PR.

Hi @opis-mark , this is due to the PR being from the fork. We increased the threshold in coveralls to address that, your next push should not trigger a failure. In the future we will change the test coverages to not run on non-code change.

Really awesome PR, thank you so much @opis-mark !
