Moving all operator packages to requirements. These packages are installed during server start, so there is no reason to keep them in separate files.

• This prevents system-wide root pip install that can damage linux machines. Packages will get installed in venv.
• This also makes package management easier from one place.
• Package dependency checks can later be performed to remove unused packages (if that was a reason for keeping operator packages within specific files).
