Consolidate portmapping

Consolidate portmapping

- creation of logical-connection-point for DEG and SRG roadm-external
ports by TransportPCE, from device configuration datas, when
configuration is relevant
- for unidirection ports, check their consistency before lcp creation,
using among other things partner-port information
- for XPDR, partner port is added in portmapping through partner-lcp.
For ROADM, partner ports are distinguished with lcp-termination (TX or
RX)
