LocalFeeder Changes

• Adds new publications and subscriptions in the LocalFeeder for setting PV (set PV) which takes a list of pvsystem, p, and q. (i.e. no new types). The new publication reports available real power at each PVSystem.
• Changes how available power was defined to better report information on IrradianceNow instead of Irradiance
• The feeder is now guaranteed to run until the time t = # of time steps - 1 instead of simply that number of steps.
• a tap setting which forces all transformers to tap={tap_setting} if defined.

CI:

• Adds a new CI step for OMOO test along with an analysis script opf_analysis.py

OMOO:

• Fixes OMOO.py script produces singularity error #47
• Fixes problems with initial max Q set point
• Fixes problems related to available PV power in original code (but requires correct kV ratings on PVSystems)

Scenarios:

• Adds omoo to components.json along with a scenarios/omoo_system.json.
