When going through the example config files, some issues were found. For example, `development-gosdn.toml.example` contains the following old or unusable parameters:
- cli_pnd = '0455b241-5863-4660-ad15-dfde7617738e'
- cli_sbi = 'a249f2d2-f7da-481d-8a99-b7f11471e0af'
- config = '/home/neil/code/gosdn/controller/configs/development-gosdn.toml'
- csbi-orchestrator = 'localhost:55056' (unsure?)
- maybe there is more in other files, pls also check them
