Trigger logging

Triggers are simple DI enabled services, therefore logging can be enabled using

public class MyComplexTrigger : IBeforeSaveTrigger<Customer> {
    readonly ILogger _logger;

    public MyComplexTrigger(ILogger<MyComplexTrigger> logger) {
        _logger = logger;
    }

    public Task BeforeSave(ITriggerContext<Customer> context, CancellationToken cancellationToken) {
        this._logger.LogInformation("Something is happening!");
    }
}
