Reload config involves a loss of logs

[sebastiendejou]

Is your feature request related to a problem? Please describe.

When an update of the fluentd's configuration happens from another namespace, the fluentd worker process is restarted. (this way : http://127.0.0.1:24444/api/config.reload) and the problem happens : Logs are lost during reload for the first namespace.
Does logging-operator respect the multitenancy agreement ?

Describe alternatives you've considered
No one.

Describe alternatives you've considered
In a previous issue, "/api/config.gracefulReload" (#454) has been suggested. This issue has been merged, but reverted after that.
Is there a mechanism that could gracefully reload the fluentd ?

It was reverted because it did not handle plugin params as expected. Things might have changed with latest fluentd versions though. I would consider making this configurable and let users experiment with it until we can get back to this and retest it thoroughly.

@sebastiendejou or anyone else still have any interest in trying gracefulReload? If yes we can implement a flag for that.
