Add sensor instance id command line argument.

Introduce `-i|--sensor-id` flag to explicitly set sensor
suffix for dbus name.

Sample usage:

   phosphor-hwmon-readd -i test_sensor_id -o /apb/...

Will register the service with the following busname:

   xyz.openbmc_project.Hwmon-test_sensor_id.Hwmon1

This change required as a part of privilege separation work:
