sorry about this. @rwood-moz, you can just change it to bt to bluetooth.

I was just worried about this could be too long.

suggested to change:
bt_set_device_bluetooth_name -> bluetooth_set_device_name
bt_set_device_bluetooth_discoverable_mode -> bluetooth_set_device_discoverable_mode

Also, if you can merge current gaia_test.py, and help me to modify it to:
bt_enable_bluetooth -> bluetooth_enable
bt_disable_bluetooth -> bluetooth_disable
bt_pair_bluetooth_device -> bluetooth_pair_device
bt_unpair_all_bluetooth_devices -> bluetooth_unpair_all_devices
bt_is_bluetooth_enabled -> bluetooth_is_enabled

I would appreciate your help. Sorry for my inconsidarate on the naming.
