propose: Allow execute functions

[crhdev]

Hello, in this commit: crhdev@83b5841 , I was playing a little to be able to allow the execution of functions instead of cake command. In my application, I have some use cases where creating a command is unnecessary. Do you think it may be possible to integrate something like this?

    public function schedule(Scheduler &$scheduler): void
    {
        $scheduler->execute(function($a, $b, $c, ConsoleIo $io) {
            $io->info('Sum');
            return $a + $b + $c;
        }, [1,2,3])->everyXMinutes(1);
    }

So you don't test these kind of functions?

I don't really like breaking this kind of structure since commands are really easy to make via bin/cake bake command and thats it.

Especially since all that Command class needs to have is the execute method. You can just remove the buildOptionParser method if you don't need it.

Sorry, the example I gave was basic.
Maybe something like:

 public function schedule(Scheduler &$scheduler): void
    {
        $scheduler->execute(function($a, $b, $c, ConsoleIo $io) {
            $service = new CriticalRenewAuditLog();
            return $service->run($a, $b, $c);
        }, [1,2,3])->everyXMinutes(1);
    }

In this case, we have a test for CriticalRenewAuditLog class.

For some security reasons (that I don't know), in my team, it is not allowed to create cake commands for certain things since they could be invoked by other parts of the development team, for example the 'system administrators', since they can log in the container/server/whatever and execute them by hand with ./bin/cake etc...
