* Improve Components error handling
* Change event handlers IHandleEvent, IHandleAfterEvent to be async.
* Return faulted tasks to Renderer instead of handling exceptions in ComponentBase
* Use ILogger in RemoteRenderer, and log to console in WebAssemblyRenderer
* Cleaning up touched files
Fixes https://github.com/aspnet/AspNetCore/issues/4964
* Updates the IComponent interface to rename Init into Configure
* Updates the IComponent interface to change SetParameters for
SetParametersAsync and make it return a Task that represents when the
component is done applying the parameters and potentially triggering
one or more renders.
* Updates ComponentBase SetParametersAsync to ensure that OnInit(Async)
runs before OnParametersSet(Async).
* Introduces ParameterCollection.FromDictionary to generate a parameter
collection from a dictionary of key value pairs.
