Remove a function added by a client but with no workers for it
There is a situation in which a client will ask the job server to preform certain function, however if the worker is not connected, all of those jobs are left within the job server. And so, when the worker is connected it is flooded with all those jobs for that function.
The idea is to add a command which will be able to remove a certain function for which there are no workers presenting in the moment.
I have already implemented the feature and I'm testing it in the moment
