Motor controller, Axis: support custom 'mandatory config. parameters'
(issue raised while working on Micros controller with Franc)
At the moment only acceleration
and velocity
are mandatory config. parameters ;
overloading get_mandatory_config_parameters()
is a first step to have custom
parameters, but there is some work to do since code in bliss/controllers/motor.py
is not ready for having a custom list of those parameters.
