Health Check for Tunneled Application Access

[DoktorAerzt]

It would be nice to add an health check to an application with runs over teleport.

When you have 2 or more nodes with server the same application it would be great when you can add a health check to each teleport node to check the local application and stop the tunneling if the application is unhealthy.
It would be enough to trigger a custom shell script with the URL as parameter and if the script exited with 1 then it means unhealthy and with a 0 it means healthy.

What do you thing?
