kong-app release v2.4.0

KIC now defaults to version 2.1. If you use a database, you must first perform a temporary intermediate upgrade to disable KIC before upgrading it to 2.x and re-enabling it. See the upgrade guide for detailed instructions.
ServiceAccount are now always created by default unless explicitly disabled. ServiceAccount customization has moved under the deployment section of configuration to reflect this. This accommodates configurations that need a ServiceAccount but that do not use the ingress controller. (#455)

Align with upstream chart 2.6.4
Default Kong IC version updated to 2.1
Default Kong proxy version updated to 2.7 Note chart versions 2.3.0 through 2.5.0 contained an incorrect KongIngress CRD. The proxy.path field was missing. Helm will not fix this automatically on upgrade. You can fix it by running:

kubectl apply -f https://raw.githubusercontent.com/Kong/charts/main/charts/kong/crds/custom-resource-definitions.yaml
