This method takes in requests and sends them through our pipelines. - Add new ***provisional*** module `azure.core.rest`. `azure.core.rest` is our new public simple HTTP library in `azure.core` that users will use to create requests, and consume responses. - Add new ***provisional*** errors `StreamConsumedError`, `StreamClosedError`, and `ResponseNotReadError` to `azure.core.exceptions`. These errors are thrown if you mishandle streamed responses from the provisional `azure.core.rest` module ##### Fixed - Improved error message in the `from_dict` method of `CloudEvent` when a wrong schema is sent.
