FIT: Switch to another Run Target

[TimoSteuerwaldETAS]

What

Verifies requirements:

• feat_req__lifecycle__request_run_target_start: Request run target launch
• feat_req__lifecycle__switch_run_targets: Switch between run targets
• feat_req__lifecycle__process_state_comm: Process state
• feat_req__lifecycle__process_termination: Terminating process
• feat_req__lifecycle__terminationn_dependency: Handling process dependency in termination
• feat_req__lifecycle__launch_manager_shutdown: Normal shutdown

Depends on: #172

Configuration:

• Configuration with the following run dependency tree:
  • Startup - which is the initial run target - depends on component component_initial
    • component_initial: No dependencies
  • run_target_a: Depends on run target run_target_c and component component_a
    • component_a: Depends on component_b
      • component_b: No dependencies
    • run_target_c: Depends on component component_d
      • component_d: No dependencies

Test steps:

• Start Launch Manager process
• Via score::lcm::ControlClient::ActivateRunTarget(..) activate run_target_a
• 1s after component_a reports running and run_target_a is activated, via score::lcm::ControlClient::ActivateRunTarget(..) Startup gets activated

Expected behavior:

• Launch Manager is started successfully and Run Target Startup is activated initially
• After call to score::lcm::ControlClient::ActivateRunTarget("run_target_a"): All involved components of run_target_a are started in the correct order from bottom up
• After call to score::lcm::ControlClient::ActivateRunTarget("run_target_initial"): All involved components of run_target_a are stopped in the correct order from top down

Acceptance Criteria (DoD)

Test specification and implementation exists. Test passes.
