class NullLogger in Service Container 7

This Logger can be used to avoid conditional log calls

Logging should always be optional, and if no logger is provided to your library creating a NullLogger instance to have something to throw logs at is a good way to avoid littering your code with `if ($this->logger) { }` blocks.
