Create sanity test to run against Thundermail stage

[rwood-moz]

Create a sanity test which is a subset of the existing integration tests that will validate the very basic functionality of JMAP/IMAP/SMTP/CalDAV/Cardav on Thundermail stage. Have the ability to run the new sanity test against Thundermail stage by triggering it manually via a Github Actions workflow. Fixes #205.

Very cool! Looks good, and I got to learn about custom metadata markers in pytest. Thanks!
