Option to include timestamps on logs

[milas]

Describe the Feature You Want

• Option for Tilt to show timestamp next to each log message

Current Behavior

• Tilt does not display timestamps for logs

Why Do You Want This?

Not all apps are configured to include the timestamp in their log output, especially if using a "pretty" format for dev, so it's helpful to have additional context when debugging.

Apparently, this has been implemented in some way in this PR. However, it was then reverted by @nicks in this other pr, who mentioned that they're "going to implement it at render-time". Unfortunately, no relevant issue has been linked and I haven't been able to trace the intention to re-implement this in any of the issues. Would be great to have a way to add timestamp to every log line Tilt is generating.
