changing cf CLI trace stream from stdout to stderr

Koper, Dies <diesk@...>

Hi friends,

Currently, the cf CLI trace when enabled ("CF_TRACE=true", `cf config -trace true` or with the `-v` option) is directed to stdout.
Looking at other commands, e.g. `curl -v`, it's common to send such information to stderr.
This recently came up in the following issue.

I'd like to know whether anyone would be massively inconvenienced if we fixed this to make cf CLI trace output go to stderr (e.g. because you have many scripts expecting trace to be streamed to stdout, or not expecting anything but errors and warnings to be streamed to stderr)?
Note that trace configured to output to a file would not be affected.
