Refactor PCE network analyzer PceOtnNode step 2
second pass to prepare deeper refactoring of PceOtnNode class:
- use Map or List to check and manage ODU and Eth service types
instead of switch/case and if condition blocks with multiple checks
- rationalize namespaces use and import
- refactor a few checks and indentations
- point with TODO comments places where
* some missing service types might be managed
* some checks are similar to existing methods
* some new methods would help
