OkHttp Builder Exposed for REST and AWS (#628)

* Update some dependencies

* Direct access to ParseOkHttpClient since it is the only one

* ParseOkHttpClient becomes ParseHttpClient

* Remove ParseNetworkInterceptor in favor of OkHttp interceptors

* Modify tests that need Plugin teardown to do so to prevent random tests from failing

* Joint support library version

* Add back in checkinit

* Remove AWS client builder (build the http builder instead). AWS -> File

* Fix ParseFileRequestTest

* Reset in between test cases in ParseCloudTest

* Add plugin resetting to both the setup and tear down of tests
