config: seed plant params from Pot.water_mass at server startup

Browse Source 
Sud._parse_data now falls through to pot_config for all hardware keys
(mass, material, L, Td) — EMPTY_SUD no longer shadows them. brewpi.py
seeds pot/tc plant params from Pot.water_mass on startup so the
simulated plant is configured before any sud is loaded.
