TAPI topology consolidation - step2

TAPI topology consolidation - step2

- integrate into T0 mulilayer TAPI topology the 100GE Transponders when
  their network ports are connected to the ROADM infra through
  xponder-input/output links
- manage the client to network port association for the 100GE
  transponder case
- adapt ConvertORTopoToTapiTopo and TapiTopologyImpl classes to add new
  UT for the 100G transponder use case
- rationalise samples of xml files to adapt portmapping and topologies
  to new test cases with 100GE transponder
- separate in a dedicated test file UT testing TAPI exceptions
