Commented Task: API Review Feedback: Interceptors [1404]

Implement changes to interceptors based on API review feedback.
Comments: Resolved in 36052d611357 From YF-12A to SR-71 (Interception API review updates) This change includes all the updates based on interception API review. Specifically: - Move to Infrastructure.Interception namespace - Rename Interception to DbInterception - Rename AddInterceptor/RemoveInterceptor to Add/Remove - Rename Dispatchers to DbDispatchers - Moved Async to append instead of prepend dispatcher methods - Made CancellationToken the last parameter for dispatch methods - Rename DbCommandLogger to DatabaseLogFormatter - Made Context and Stopwatch protected - Added Stopwatch documentation - Renamed Sink to WriteAction and made internal; added Write method - Removed DispatcherBase - Collapsed DbCommandInterceptionContext classes and renamed base - Removed DbCommandTree from command tree interception--just use interception context instead - Renamed IsSuppressed to IsExecutionSuppressed Also included here are updates to DbConfiguration exception messages which I missed in the previous checkin.
