Isaku Yamahata 0dd34df455 lib/quantum: refactor quantum plugins and third party 
As quantum plugin support is coming like floodlight, nvp and nec,
it's worth while to refactor quantum plugin logic so that each plugin can
be modified/enhanced intervening with other quantum plugin.
And new plugin support can be added easily (hopefully) without modifying
core logic.

    • The corresponding file name should be same to service name, <third_party>.

lib/quantum calls the following functions when the <third_party> is enabled

  • install_<third_party>: collect source and prepare e.g. git clone xxx

  • start_<third_party>: start running processes, including screen e.g. screen_it XXXX "cd $XXXXY_DIR && $XXXX_DIR/bin/XXXX-bin"
