Collect suite of projects for KBT-handling consistency testing across updates

[Enkidu93]

If we have a small suite of projects that are representative of different potential KBT set-ups, we can run terms extraction against these projects at intervals and confirm that:

• Behaviors have not changed across updates
• Behavior is consistent across silnlp/Machine/machine.py/Serval (until, of course, they are both sharing the same Machine implementation)

I've been thinking that we should create a directory in the bucket for projects that we use for this sort of testing. That way, the projects don't change over time and we could give them names that don't include any country or language information, so that we could reference them in automated tests as well.

@mmartin9684-sil, is this something you could help me assemble?

I'm sure we'll want to cover at least all the key terms list types as well as languages that do and do not have gloss support. Are there any categories you can think of that I may not be thinking of?
