R/JGF disagreements

[jameshcorbett]

rv1 and JGF can sometimes disagree on what properties a node has, and also what rank it represents. This can lead to very ugly problems.

For instance, if nodes are given queue properties in R but node vertices in JGF don't have those same properties, jobs will never be scheduled, but no error occurs (see #1350). Also, nodes can be given ranks in JGF that don't align with their ranks in R, raising execution-time problems.

For properties, one idea would be to add all properties from R in addition to whatever properties are found in JGF. Ranks should be validated.

See also #1219, for some discussion of a case where this occurred.
