Have the NuGet package include all dependencies when downloading on the client machine

[Arash-Sabet]

The following packages must be added manually when the SDK is added to a client project:

• Microsoft.AspNetCore.Http.Connections.Client
• Microsoft.AspNetCore.SignalR.Client
• And probably Microsoft.AspNetCore.SignalR.Client.Core

The BuildAsync(...) would including the missing packages' information in each subsequent calls which is cumbersome. We need a way to get the dependencies downloaded when the SDK is referenced.

Possible helpful articles and posts:

• Build NuGet Package automatically including referenced dependencies

Reopened this issue because the ChatSuite server's integration tests still require adding the referenced assemblies (nuget packages) manually after releasing ver 1.0.2.
