List servers with package upgrades pending

[SwimGeek]

Is your feature request related to a problem? Please describe.

I often use this command to see which servers need package upgrades:
salt '*' pkg.list_upgrades

But, this creates a very long list of all the packages on all the servers.

Describe the solution you'd like

It would be nice to run something like:
salt '*' pkg.list_servers_with_upgrades_pending
To only get a list of servers which are in need of upgrades.

Additional context

Every time there is a Debian point release, I have to log into each server and upgrade it manually.

Are you talking about something like a summary ? I think you can do it yourself using a runner.

Hi, not sure what a runner is. Do you have an example command?

I'd like a command I can run to list all servers which have one or more upgrades pending.
