Merged PR 628229: Add AMQP head with SAS authentication support This PR should be considered as _in progress_ right now. While the SAS authentication is implementation complete, I haven't really tested it with a Device SDK client because there are other pieces that need to be in place before we can do that. The following files in this PR are there only to make stuff compile and isn't ready for review: 1. AmqpConnectionGatewayContext.cs 2. AmqpRuntimeProvider.cs Begin the review by reading `/doc/AmqpBootstrapImplementationNotes.md`. That should give you an idea about how AMQP SASL authentication works. `AmqpProtocolHead.cs` is the entrypoint - this object's `StartAsync` method is invoked when the Edge Hub service starts. `EdgeHubSaslPlainAuthenticator.cs` contains the code that implements SAS authentication.

Merged PR 583636: Merge angelod/ModuleToCloudSequenceDiagram to master I will add the sequences Diagrams and updating the Class Diagram on the visio file, before referencing it on the documentation. If we find value on publishing it, we can update the .md file pointing to them and keep updating it.

Merged PR 576875: Merge angelod/updatingDocuments to master The goal of this 1st PR is to ADD the Visio Diagram document to our repo, so everybody can edit and make changes to our design doc for Edge Hub. So, this change has: -Very minor fixes that I have identified; -Adding Class Diagram do our main Readme file; -Renaming tabs on our visio diagram file. *This PR does not update the overall design, since this is a large effort and should be done by whoever change the code or has more specific knowledge.
