This PR updates Ohm's law constraint statement in all current OPF models, to ensure that the constraints always have the form
<some combination of other variables> - pf == <constant>
Note that <constant> is typically 0, and that I use pf above to denote to/from active/reactive power flows.
The goal is to have a unified convention for Ohm's law duals across the various OPF problems.
Compared to the current setting of writing pf == <some function of other variables> + <constant>, this PR will effectively flip the sign of the dual variables associated to Ohm's law constraints.
