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

There is no metric which captures the uptime of processes running on a host.

Describe the solution you'd like

There should be a metric like process.uptime which should display the pid, elapsed time and command as dimensions.

Describe alternatives you've considered

Currently we use telegraf to capture the output of ps -eo pid,etime,comm.

Pinging code owners for receiver/hostmetrics: @dmitryax @braydonk. See Adding Labels via Comments if you do not have permissions to add labels yourself. For example, comment '/label priority:p2 -needs-triaged' to set the priority and remove the needs-triaged label.

Since this now exists in our semantic conventions we can add it in the process scraper. I will find some time to do this soon, unless anyone else would like to contribute it.

Hi @braydonk / @dmitryax ,
Is there a possibility for anyone of you to have a look at this one?
