Support 5GTANGO package format

[mpeuster]

Make use of 5GTANGO package and unpackaging. Would be a perfect fit here and reduce development overhead if only done once.

tng-profile will work on project strcutures!!!

• ensure installation of tng-sdk-package during setup
• add new generator module tango.py

Implement Generation Process

• unpack the input *.tgo to a temp dir base_service
• generate projects using base_service
  • add mp connection informations to example PED
  • copy projects
  • gen: add mps
    • add MP VNFDs to project
    • update NSD: functions, connection points, links, VNFFG
  • gen: add resource limits to VNFs
    • for each VNF, find VNFD
    • overwrite field in VNFD
    • store new VNFD
• walk over the generated service projects and call the packager
• add unit tests for generated projects and packages
  • split unittests to separated files
  • generate dummy ex/ec and let it update the example service, then check the project folder if the NSD and VNFDs are changed as they should
• return: NOTHING (everything is added to the ec's in each ex)
• print generator statistics
• refactor init.py

Examples:

tng-bench -p examples/peds/example_ped1.yml

tng-bench -p examples/peds/example_ped1.yml -v --no-execution
