George can view all of Manticore's states and their status

[Sonya]

Why:

George needs to know what's running and its status.

Acceptance Criteria:

• When Manticore is running, a MUI side-panel is shown
• The side-panel shows a list of states and their status
  • We show what is currently being executed by Manticore as an "Active" state in the list
  • We show a queued state as "Waiting" in the list
  • We show a forked state as "Forked" in the list
  • We show a state that has exited normally as "Complete"
  • We show a state that has exited in any other way as "Errored"
• George can see the ID of the state in the list
• The status and states are updated at an interval
• George can scroll to see all of the states

Note:

We have some initial implementation for Manticore introspection for the TUI feature.

We are going to need to generate Java code from the protobuf specification for Manticore's introspection data
