gazebo_yarp_maissensor: Expose data via yarp::dev::IEncoderArrays and add support for disableImplicitNetworkWrapper, yarpDeviceName and sensorName parameters

[traversaro]

Fix part of robotology/icub-models#234 . The only missing part to understand is which name to return in the getEncoderArrayName, waiting for feedback in robotology/icub-models#234 (comment) to proceed.

Inspired by robotology/icub-main#905 .

Some failures are unrelated to the PR (#687 and #686).

This was fixed, now the value returned by the getEncoderArrayName method is specified by sensorName argument as in this specific case we do not have any sdf sensor corresponding to the main/array encoder, so we need to specify the sensor name in some other way.

If you need to migrate existing instances of gazebo_yarp_maissensor to use MAS interfaces and gazebo_yarp_robotinterface, use robotology/icub-models#240 as a reference.
