Allow resources in rules evaluation (i.e., repeated reevaluation of resources)

[martindemko]

Hi,
As discussed on the matrix, I'm reporting this error:

The following example doesn't work, and it would be great if it could:

rules:
  if: mem > 180
    scheduling:
      require:
        - highmem

Thank you,
