Some CI improvements

[etpinard]

This PR splits our jasmine test suites (which is getting pretty heavy 🍔 ) into 2 separate CircleCI jobs: one for our gl3d, gl2d and parcoords tests (tag @gl) and another for all the other tests that aren't skipped on CI (that @noCI tag).

This does two things:

• speeds up our tests, they now run consistently under 10 minutes
• (hopefully) will help us with our intermittent test failures (gl tests seem to behave better in isolated runs for some reason).

Moreover, the PR removes a few @noCI tags from our suites. Upgrading to Chrome 64 in #2323 made some tests work on CI. To note, @monfera almost all your parcoords tests are runned on CI now.

Nice! So previously we had:

Executed 2382 of 2454 (skipped 72)

Now we have:

Executed 2326 of 2452 (skipped 126)  // jasmine
Executed 81 of 2452 (skipped 2371)   // jasmine2, (gl)

ie total 45 skipped, or 27 more tests than we used to run on CI 🎉

Most of those are mapbox, so there are just a few that we might want to continue to investigate later.

No changes from me, this looks great! 💃
