Hello.

Given how the new automated backup system works in Moodle, see forum Moodle in English: Force run adhoc task, I was wondering if its possible to allow certain adhoc tasks to get priority over others.

For example

There is a time in a year where we prepare for the new semester and we would like the task `core\task\asynchronous_copy_task` to be given priority over all other tasks.

I would suggest to have something similar to 
$CFG->task_concurrency_limit
 
So, we would be allowed to add an array of tasks that should be run first before any other adhoc task.

Any feedback on this?
