Sort requested resources by user defined groovy script

### What feature do you want to see added?

When the resources are requested by label, it is possible to pick resources randomly or just by index, when there are added.

It will be great to provide a feature to sort the resources by user defined groovy script.

ex:
name | labels
resource1 | nwcard:1 nwcard:2
resource2 | nwcard:1

```
def sortScript = { if (resource.hasLabel('nwcard:2') return 0; else return 1; }
lock(label : 'nwcard:1', quantity : 1, sortBy : sortScript) { echo 'I am locked') }
```
