3: Refreshing the control console browser interface breaks the ping process interface

In control console browser interface, if you start the ping, then you refresh the page, there is no way to stop or restart the ping process anymore.

By design, when we refresh the refresh the control console page, the index.html defining the page is sent again to the browser and builds everything again from scratch. We don't handle yet the "page refresh" scenario. We should:

• either stop ongoing processes and close the port connections prior starting everything again,
• either recover eventual existing connections or ongoing processes, like the ping, when rebuilding the page.

This is the enhancement to be done through this issue.
