Hey folks,

Simple (hopefully?) feature request for the Nomad remote exec web UI:

We run our Nomad cluster behind an AWS application load balancer that serves the UI and API. The ALB has a connection idle timeout, which by default is 60 seconds. So, basically, if you open a remote exec session, it will only stay open as long as there's either input or output from the session - otherwise, it terminates after the timeout expires.

It would be helpful for Nomad to have a "keep-alive" function for exec sessions to prevent issues like this.

Thanks for the suggestion, @jfcantu. It does seem simple enough to implement in the UI, though I’m wondering if it should have CLI support as well, then both consumers could use the same flag. I’ll ask around about this.

Add exec heartbeat keepalive

This closes #8727, thanks to jfcantu for the suggestion.
The CLI implementation of exec already has a 10-second
heartbeat so this mirrors that:
