Task triggers (ie deploy)

[kbond]

Ability to add tasks to a "trigger group" like deploy:

class AppScheduleBuilder implements ScheduleBuilder
{
    public function buildSchedule(Schedule $schedule): void
    {
        $schedule->addCommand('app:warm-cache')
            ->trigger('deploy')
            ->unscheduled() // disables task from bring run except when "triggered"
        ;

        $schedule->addCommand('app:health-check')
            ->hourly() // also runs hourly
            ->trigger('deploy', priority: 10) // would run before the above task
        ;

        // ...
    }
}

Run the trigger (ie in a post deployment script):

bin/console schedule:trigger deploy

Combined with #58:

#[Schedule('@daily', trigger: 'deploy')]
class MyService
{
    public function __invoke()
    {
        // ...
    }
}

#[Schedule('@weekly', trigger: 'deploy')]
class MyCommand extends Command
{
    public function execute(InputInterface $input, OutputInterface $output): int
    {
        // ...
    }
}

A dedicated Trigger attribute could be added to make unscheduled invokable service/console command tasks:

#[Trigger('deploy')]
class MyService
{
    public function __invoke()
    {
        // ...
    }
}

#[Trigger('deploy')]
class MyCommand extends Command
{
    public function execute(InputInterface $input, OutputInterface $output): int
    {
        // ...
    }
}
