Explain why GrpcSecurity is not available in a servlet app

[dsyer]

Users can be confused when GrpcSecurity is not available because they have a GrpcServlet (they should use the normal web MVC security in that case). The best thing to do is probably provide a failure analyzer that recognizes the scenario where user tries to inject GrpcSecurity but it isn't available despite being on the classpath.

Hi, @dsyer. I suppose we could add something like custom AbstractFailureAnalyzer to the autoconfigure module and implement the corresponding logic in our scenario?
I can work on this. Could you assign me?
