Core Next Minor - one of DedicatedConnectionOrTransactionDbDistributedLock's constructors can be internal

[madelson]

        public DedicatedConnectionOrTransactionDbDistributedLock(
            string name, 
            Func<DatabaseConnection> connectionFactory, 
            bool useTransaction,
            TimeoutValue keepaliveCadence)

This constructor is only referenced from Core itself, so no need to make it visible to the implementation layer.
