Remove Configuration interface prefix from utils APIs

This eliminates some repetitive verbosity from daemons that handle a lot
of different sensor types (such as hwmontempsensor and psusensor).  It
also positions us to more cleanly use a single data structure for both
existing APIs like GetSensorConfiguration() and
setupPropertiesChangedMatches(), as well as upcoming I2C
device-management support.

Tested: hwmontempsensor and adcsensor on romed8hm3 continue to behave as
they did previously.
