Run tests on Java 17

[carterkozak]

Tests are failing since atlas hasn't upgraded to Gradle 7 yet

Is anyone looking into taking the plunge?

Goals (and why):

Latest LTS release, I'd like to verify atlasdb can pass tests before upgrading products that use atlasdb code!

Implementation Description (bullets):

Using the new baseline java versions plugin to set java versions for libraries, and the version to use for tests

Testing (What was existing testing like? What have you done to improve it?):

This is that :-D

Concerns (what feedback would you like?):

Where should we start reviewing?:

Priority (whenever / two weeks / yesterday):

I was OOTO from last week Friday. Will get to this at some point this week.

Gradle 7: @sudiksha27 is actually in the process of doing it!
