[IMP] netsvc: add remote_logging capability

[ap-wtioit]

Description of the issue/feature this PR addresses:
enable RFC5424 compliant remote logging in odoo

Current behavior before PR:
Odoo is only able to log to the file system with the --syslog option

Desired behavior after PR is merged:
Odoo is directly capeable to transmit logfiles to an RFC5424 compliant log server (e.g. Graylog2), which enables to transmit more information to the server (like line number and file)

Any chance to get this in 12.0?
Worth a lot IMHO and "just" an option...maybe you can do a short review to get some feedback.

Hi,

It's a good idea and definitely worth looking at, however I doubt it can be merged for 12.0, for various reasons, one of them being that we decided not to add any more CLI options until its refactoring takes place (unless strictly necessary), which is not a priority for v12 and currently has no ETA

[odony]

Sorry, what's wrong with using the log shipping facilities of syslog? That's what we're doing whenever we need to send log remotely. If you need remote logging, chances are you won't just be shipping the logs of just one application, but other processes and system logs as well. Hence centralizing through syslog makes sense. Why would you want to reconfigure it in each application, including Odoo?

[odony]

Structured logging does not seem worth extra custom code in standard. Have you tried providing this facility has a separate module? A PR that makes pluggable logging facilities could be more easily accepted.
Odoo is huge enough to maintain, we tend to avoid including code that we don't plan to actively use ;-)

@odony
Thank you for your appreciated opinion and feedback.
Nothing is wrong using syslog itself, but having structured output without the need of parsing syslog was the reason why we directly send the logs remote.

As I am super happy ^^ and excited about the centralized, indexed and custom structured log facility I thought it is worth proposing and open it for discussion. Of course doing a plug-able module would make it sexier, but as @Elkasitu said, we probably wait here for the time when this part of code becomes priority for you guys too.

Not sure if there is really a lot to maintain here, but as always you have an argument and maybe we might have a little talk about it in person in a few weeks to understand each PoV a bit better ;-)
