/*
 * AMQP has a SASL authentication mechanism that doesn't match
 * with existing .NET credentials.  The analogy breaks down further
 * if there is a list of brokers to cycle through on failover.
 * This class will allow arbitrary credentials to be specified
 * by the user, but is meant to be sensibly populated by bindings
 * that use it from ClientCredentials.
 * See the related interplay of ClientCredentials and
 * WebProxy NetworkCredential for the BasicHttpBinding.
