[Pulp-dev] Proposal to change default logging to console in Pulp 3

[Brian Bouterse]

I think console logging is also probably the right logging default in non
containerized environments too. The majority of OSes Pulp will run on will
run systemd which has it's logging facilities reading from stdout and
stderr [0]. So for the majority of non-containerized userbase systemd is
their logging system not syslog. Not to say syslog is dead, it's especially
useful for clustered installs which need fancier logging like
centralization or off-site replication, etc. Those users can take the extra
step to configure logging to syslog if they apply a bit of extra config
after https://pulp.plan.io/issues/3879 is fixed.

It also being the expected logging for containerized environments makes me
think we should switch Pulp3 to console logging as the default. What do you
think?
