bridge (constructor): refactoring:

- constructors are now in separate modules
    - constructors are discovered dynamically
    - factorised generation code from D-Bus in base Constructor.
    - A generic generation method is now available in base Constructor, using python formatting.
    - removed bridge/bridge.py in core as it was useless, may come back in the future if needed
