Add target interface for fan monitor
Current fan monitor assumes the use of the FanSpeed interface for fan
targets.
For fans controlled by pwm, FanPwm interface is added.
This commit adds a "target_interface" config parameter, so that user
can specify the interface for the fan targets.
E.g.
- name: fan0
has_target: true
target_interface: xyz.openbmc_project.Control.FanPwm
This config is optional and defaults to FanSpeed, so the current code
will not be affected.
Tested: Use this config on Romulus, ensures fan monitor gets fan
target from FanPwm interface and works OK.
