Prototype package manager with new console manager

Test Procedure:

Different Part:

• With UE4

  • Prepare UE4 SIM without start play
  • Start sim_vehicle
  • go to script/testing, lunch sim_ue4.bash, follow the printed instruction
  • go to launch, roslaunch ./StartCore.launch

• Without UE4

  • Start sim_vehicle
  • go to launch/sitl, roslaunch ./step1SITL.launch
  • go to launch, roslaunch ./StartCore.launch

Shared Part:

• Now you have Package Manager(PM) and Console Server(CS) started
• Launch the main node by pm launch main / pm launch

Tests 1:

• Check existing functionalities still work, play with cnc, so on
• Check popups still work
• Check OA still work (require UE4 SIM)(Note: RRT if configured to only accept command within 10 meters range (e.g. ! w 9) due to performance issue, long-range fast OA will require @DanielXu 's FGM algorithm)
• Note: WebGUI will require some modification (topic name, we can change it after this got merged)

Test 2:

• Play with the PM and CS
• Try help command
• Try to install the sample app (https://gitlab.tuotuogzs.com/shibohan/pm_test_app)
• Try to uninstall
• Try list
• Note: please only try sample apps master branch for now

Before reporting an issue, make sure the current master is still working, because we didn't test it for quite a long time.
