Subject: [PATCH] Fluent-logging: Update default fluentbit configuration

As of 0.12.14, fluentbit exposes a flag for setting the db_sync
behavior for writing the location of the tail input to its sqlite
database. The default setting is Full, which introduces additional
synchronizations before and after a transaction. This has the
potential to negatively affect disk performance with the extra
synchronizations. This moves the setting in the chart to Normal,
which performs fewer synchronizations and still maintains a high
level of safety with status writes
