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
the callback receiver is still fairly slow when logging is enabled due
to constant setting lookups; this speeds things up considerably

refactor existing handlers to be the related
"real" handler classes, which are swapped
out dynamically by external logger "proxy" handler class
real handler swapout only done on setting change
remove restart_local_services method
get rid of uWSGI fifo file
change TCP/UDP return type contract so that it mirrors
the request futures object
add details to socket error messages
* Change scheme from using event dict to JobEvent object
* Add processing to grok object fields
* Allow override of provided formatter in case of future issues
The handler and formatter classes are expecting an object
and the previous method passed a dict, so this change converts
the data into a mock settings object.
This separates file parsing logic that was mixed
in with other important code inside of the
inventory import command.
The logic around MemObject data structures was
moved to utils, and the file parsing was moved
to a legacy module. As of this commit, that
module can operate within the Tower environment
but it will be removed.
Also refactor the loggers to fix old bug and
work inside of the different contexts - the
Loader classes, mem objects, and hopefully
the inventory modules eventually.
