Portmapping-topologies code consolidation

Portmapping-topologies code consolidation

Refactor otn-topology code to avoid any access to OpenROADM device
configuration during node creation. To that purpose:
- review code related to all topology layers to use static methods
- add new class OtnNode to help creation of different otn-nodes in
  otn-topology
- change code to create otn node in otn-topology distinguishing tpdr,
  switch, mpdr
- adapt openroadm-topology to make appear network tp of otn switch/mpdr
  nodes
- remove from openroadm-topology tail-equipment-id for xpdr nodes
- adapt pce code consequently
- add tail-equipment-id with ROADM-SRG-PP info on tp of xpdr node when
  creating XPONDER-INPUT/OUTPUT links in openroadm-topology
- adapt functional tests consequently to all these modifications
- deactivate test 33 from end2end functional tests since the deletion of
  the "tail-equipment-id" from the topology is not fully implemented yet
