Change/Uniform names of YARP devices wrt WBD

[pattacini]

          Just as follow up comment,  to avoid confusion related to we may consider change/uniform the names of YARP devices between:

• yarprobotinterface of the simulated robot
• yarprobotinterface of the wbd running outside of gazebo

At the moment ergocub_left_leg_ft is:

• on yarprobotinterface of the simulated robot is just the name of the device that exposes the l_leg_ft_sensor sensor (see https://github.com/icub-tech-iit/ergocub-software/blob/facf5a613d602cb5ccb42270f248a998a0001ee8/urdf/ergoCub/conf/FT/gazebo_ergocub_left_leg_ft.ini#L2C16-L2C35)
• in yarprobotinterface of the wbd running outside of gazebo, it is the name of the multipleanalogsensorsclient that exposes the l_leg_ft_sensor, and l_foot_rear_ft_sensor, l_foot_front_ft_sensor sensors

  <device name="ergocub_left_leg_ft" type="multipleanalogsensorsclient">

Having the same name for such different devices may be source of confusion also in the future.

Alongside @traversaro we decided to not do this change:
