class NullLogger in Service Container 7.2

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.
