Ability to merge multiple logs in the UI

[dfeyer]

First, thanks for this awesome tool. I have a feature request, when I have a few starred resources, it can be useful to select more than one (double clic, shift clic, or just toggle clic), to be able to have a merged log stream from the selected resources.

In micro service architures it's nice to be able to watch stream accros a selected resources group, but most of the time "All resources" are too chatty.

I've tried myself to do this (select multiple resources in UI and was hoping for the logs to be multiplexed). Would be pretty useful it seems.

I'm using the CLI to get this exact functionality using tilt logs service_a service_b -f.
It would be awesome to get this from the UI.
