Document adapterOptions on REST adapter

[sandstrom]

Seems like we aren't documenting adapterOptions for query and queryRecord in the JSONAPIAdapter.

I've just mirrored the code in the regular adapter:
https://github.com/emberjs/data/blob/master/packages/adapter/addon/index.ts#L248

There are already tests for this, see:

data/packages/-ember-data/tests/integration/adapter/store-adapter-test.js

Line 1526 in ff4f911

test('store.query should pass adapterOptions to adapter.query ', function(assert) {

Support for adapterOptions has existed for quite a while, it was initially added in this PR: #4856

Thank you! This looks g2g after lint fixes.

Thanks @igorT I hadn't gotten to it yet 😄

Also, have you thought about joining the Github sponsorship program? We'd like to donate to some of the core Ember (and Ember Data) contributors, and you're definitely one of them. I know it's not much, but hopefully more companies will join in eventually.
