Call TSP endpoint to close an experiment when closing it in the UI

With this it's possible to close an experiment on the server. Upon
reception of the command the server can dispose allocated resources
hence the client doesn't need them anymore.

This change follows the TSP update provided by:
eclipse-cdt-cloud/trace-server-protocol#95

Fixes eclipse-cdt-cloud#1024
