Bernhard Kirchen b891a4c1a3 powermeter refactor: instanciate power meters with config
instead of reading the main config's powermeter struct(s), the
individual power meters now are instanciated using a copy of their
respective config. this allows to instanciate different power meters
with different configs. as a first step, this simplifies instanciating
power meters for test purposes.
