after some prolonged RFC reading and tinkering w/ rsyslogd...
cpython's SysLogHandler doesn't emit RFC3164 formatted messages
in the format you'd expect; it's missing the ISO date, hostname, etc...
along with other header values; the handler implementation relies on you
to specify a syslog-like formatter (we've replaced all of this with our
own *custom* logstash-esque formatter that effectively outputs valid JSON
- without dates and other syslog header values prepended)
because of this unanticipated format, rsyslogd chokes when trying to
parse the message's parts; AWX is emitting:
<priority>RAWJSON
...so the usage of `%msg%` isn't going to work for us, because rsyslog
tries to parse *all* of the possible headers (and yells, because it
can't find a date to parse):
see: https://www.rsyslog.com/files/temp/doc-indent/configuration/properties.html#message-properties
this is fine, because we don't *need* any of that message parsing
anyways; in the end, we're *just* interested in forwarding the raw
JSON/text content to the third party log handler
