Add 3 traits in the library to implement the methods of the 3 monitoring interfaces:

• MongoDB\Driver\Monitoring\CommandSubscriber
• MongoDB\Driver\Monitoring\LogSubscriber (not for this interface because it has only 1 method)
• MongoDB\Driver\Monitoring\SDAMSubscriber

The methods will have an empty body (no-op).

Benefit : the developers can write only the method they need instead of having many no-method in their code.

Trait names:

• MongoDB\Monitoring\CommandEvents
• MongoDB\Monitoring\LogEvents
• MongoDB\Monitoring\SDAMEvents

Usage:

use MongoDB\Driver\Monitoring\CommandSubscriber;
use MongoDB\Driver\Monitoring\CommandStartedEvent;
use MongoDB\Monitoring\CommandEvents;
 
class MyCommandSubscriber
{
    use CommandEvents;
 
    public commandStarted(CommandStartedEvent $event): void
    {
        // Do stuff for this event only
    }
}
