Performance Suggestion: "automatic" persistent solvers

[michaelbynum]

When re-solving the same model with minor changes, we may be able to "automatically" detect what changed and only update what needs updated.

I've implemented ideas like these in COEK, so we have evidence that this is feasible. A key question is whether the time needed to do these checks in Pyomo will be fast enough to call this an optimization. We can check this with the use cases I've used with POEK and COEK.
