Various changes

- Added an option to specify an SSL CA certificates file to talk to the
  Netbox API
- Enhanced GPU expansion bays inventory: internal GPU (VGA) goes into
  the blade, external GPU (3D) goes into the expansion bay
- Unified the way expansion bays are managed (GPU and drive exansion
  bays)
- Started to refactor `network` module to make it more readable
- Dependencies in `setup.py` now reads its requirements from
  `requirements.txt` to avoid double maintenance
