Code changes and documentation for end-to-end demo

[jeff-cohere]

This PR has everything that was needed to get the DTS prototype to successfully demonstrate a JGI Data Portal -> KBase file transfer, including the generation and transmittal of a manifest.

In particular:

• error handling and logging were greatly improved in order to debug lots of configuration and permissions issues
• materials for a static documentation website now live in the docs/ folder, and a GitHub Action auto-publishes docs for merged PRs
• DTS now performs Globus re-authentication flows where needed to access files on Guest Collections, per Globus's REST API recommendations
• a Dockerfile and deployment instructions were created that allow DTS to be deployed within Spin (and presumably other Docker/Kubernetes environments)

Closes #31

Sorry about the large PR, AJ. :-) A lot of it is documentation, though, so maybe that's positive? :-)
