feature: resources can be defined by algorithm or problem

[jakob-r]

It would be nice if there was a handy option to define the resources needed by a specific algorithm or problem within the definition of them. Now you just generate everything and then have to select afterwards what to start with which resources.

Further remark: Sending jobs with different resource demands in different batches might lead to underutilized queues so it would be beneficial to be able to start jobs kind of stratified.
