dbus-sdr: Add hybrid sensors stack option

Because the dynamic sensor stack doesn't support non-threshold sensors,
this patch gives way for retrieving non-threshold sensors by walking
through the sensor.yaml. However, this patch filters out any threshold
sensors written in the sensor yaml file because the current dbus-sdr
already supports them.

The sensor stack has both dynamic and static in this patch, so this new
feature is named hybrid sensor stack.

Tested: Try the SDR get command
