axis: introduce steps_position_precision to motor controllers, and use it to determine delta in _get_motion

axis: make offset and sign writable properties, raise an exception if controller cannot change dial position, improved lprint messages

Return low_limit and high_limit settings values

axis: _set_position_and_offset: offset is 0 if it is very close to 0 (floating point errors), always display message with sign and offset if position is changed

Ensure all properties are updated when asked by user, independently of a
config reload on Beacon

+ test

         reset_position has been set in jog motion
in elmo: keep track of last state in order to reply correctly
         from read_position the real position or the command position
         bug in jog negative direction corrected

on elmo controller :
debug homing procedure
correct jog range
try to sync pos after jog/home methods
added input_register and status_register to help debugging
