Add exclude meta tag

[leobeosab]

I needed a way to exclude meta because it was making my logs pretty messy and contained repeated data.

This looks good to me, as a workaround for winstonjs/winston-transport#27 (which probably won't be fixed at this point).

Just FYI, there's a winston-syslog transport that might work better for Winston V3. See issue 95 for a Papertrail config example.

Thanks! I'll look into that when we have less going on at work! Just so you know I don't have permissions to merge it in, if you want it in the repo. :) Have a good one!
