Package installation - setup script

[mtitov]

• Convert the setup scripts to use pyproject.toml only

Additional:

• Clean up the supported python versions - proposal: python >= 3.10;
• radical.pilot should be an optional dependency;
  • All plugins are loaded automatically, and each of them have their own requirements - should be explicitly set which plugins are required to be loaded automatically (either during the installation, or during the edge service start);
