Evaluate attributes given to the blahp. HTCONDOR-507

If the blahp needs to evaluate an expression, some of the referenced
attribute will probably be missing, so it will get the wrong result.
The gridmanager should do the evaluation instead.
This does not include CERequirements, which is meant to be an
unevaluated expression.
