refactor test framework

[benjaminxscott]

📝 totally optional merge - meant as a PoC for how I would do tests from scratch

This branch:

• trims the large number of test files to a small set of representative files
• squashes schemas and schemas-tests into a single repo
• removes notion of negative tests
• removes manifest file, using file globbing instead under named folders
• deprecates this repo

Clean build here on a modified travis.cfg

Which files did you trim? Was it any of the individual regression tests? IMO all of the regression tests should probably stay (along w/ our samples and whatnot) but I'm totally fine trimming back testing against all those VERIS files.

Agree w/ squashing schemas and schemas-tests

Undecided on negative tests, I can see why they might be necessary to ensure that fields were actually removed but in general are very confusing.

Agree w/ glob.

If we get further consensus I'd be OK merging.

all regression tests are kept, under /issues

veris files were trimmed

[johnwunder]

perfect. @bworrell thoughts?

@johnwunder, @bschmoker I think this is probably fine. I'm curious to know which VERIS files were removed and why (though I can guess there was just a lot of redundancy between them all).

@bworrell - all of them besides a few - lmk if it's cool to
