Upgrade Guide

Warnings

• It is seen sometimes that fluentd doesn't accept connections from fluentbit anymore. This is due to the low resource limit set to fluentd. Try increasing the limits if ever encountered. Make sure to rollout restart the fluentbit statefulsets once updated.
• Upgrade from v1.8.0 to v1.9.0 should be fairly smooth.
