Drop doctrine common

Subject

I am targeting this branch, because this is Bc.

Removing doctrine common, even if we still get it as a transitive dep is a good thing. If the project dont use it directly lets remove it, it is kind of being deprecated.

Changelog

### Removed
- Drop doctrine common dependency.

I have tried a search for doctrine common and didnt found it on the project, there are uses for Collections, Event manager, but thats on other packages.

@VincentLanglet could you do a second check just to be sure?

use Doctrine\Common\EventSubscriber;

EntityAuditBundle/src/AuditManager.php

Line 16 in 9ffd87e

use Doctrine\Common\EventManager;

EntityAuditBundle/src/EventListener/CreateSchemaListener.php

Line 16 in 9ffd87e

use Doctrine\Common\EventSubscriber;

EntityAuditBundle/src/AuditManager.php

Line 16 in 9ffd87e

use Doctrine\Common\EventManager;

Those are here : https://github.com/doctrine/event-manager/tree/2.0.x/src

And it is already a dep for this package

Just confirmed, Doctrine\Common\EventSubscriber and Doctrine\Common\EventManager are provided by doctrine/event-manager.
