cleanup task for directories

Changes in this pull request

This is a followup of pimcore#14688 as we've had troubles that still some tmp files fill up our storage.
In the above PR the solution is to delete tmp files in my understanding like following:

if a Temp-File gets created via File::getLocalTempFilePath()https://github.com/pimcore/pimcore/blob/10.6/lib/File.php#L237 then the path of the tmp file is registered and gets cleanup either by:

• LongRunningHelper: https://github.com/pimcore/pimcore/blob/10.6/lib/Helper/LongRunningHelper.php#L183
• Shutdown Function in File: https://github.com/pimcore/pimcore/blob/10.6/lib/File.php#L246

For example if the PHP process has a Segfault or if your container (in our case a Pod) has a memory overflow also the shutdown function is not executed so the tmp file lives forever in your storage.

To overcome this I implemented a simple clean up task in a general way to clean up a configured directory with all files older than a configured value. As default I added both tmp directories where old files always should be deletable.
In the same move I also cleaned up the HousekeepingTask and removed some old references where in the newly created Task is used.

It is lean against some part that exists back in V6.9: https://github.com/pimcore/pimcore/blob/6.9/lib/Maintenance/Tasks/HousekeepingTask.php#L48

This is currently a fallback if pimcore#15482 will not be merged. Then we can use this as soon we update to Pimcore 11
