Many distributed databases do not support the MySQL get_lock() function. In order to be able to support alternative databases in the future we need to abstract the use of get_lock() to the configured PDO adapter.

Instead of calling get_lock() directly all code should call a new getLock() method on the current PDO adapter which will allow locking to be handled differently for each database type. All Matomo PDO adapters should be implementing core/Db/AdapterInterface which can contain the new abstract method definition.

This should not change locking behavior for MySQL in any way.
