syslog levels reverse logging priority

[yonjah]

winston default logging priority order is ascending goes from lowest 0 (silly) to highest 5 (error)
but syslog priority order is descending from lowest 7 (debug) to highest 0 (emerg)

this means that when setting a log level for winston when using syslog
you will actually log below that level instead of above it
so setting logger.level='info' (which is the default)
will actually log debug and info but will not log notice warning and so on.

I might be missing some config to make winston reverse logging priority
but both the docs here and for winston-syslog did not mention any such option
