Should all tools accept all logging options?

[bradgrantham-lunarg]

There's no current way to tell convert to output only WARNING, so for a trimmed capture it will output strings like [gfxrecon] INFO - Finished loading state for captured frame 100 within the JSON output, corrupting the JSON. Also no way to tell convert to send output to stderr (which could then be sent to /dev/null using shell redirection).

There are many options available to replay that are just not passed from convert to Log::Init. If we plumbed those options for all the tools we could have more control over the log noise. (Are there other options that should be plumbed for all tools?)
