MariaDB container volume mounts are incorrect

[corneil]

Description:
The volume mount for mariadb deployment was created with /var/lib/mariadb and results in a blank database after a restart because the mount path is expected to be /var/lib/mysql

Release versions:
2.8.x

Fix
The correct mount path is /var/lib/mysql

I understand the need for the fix, in that if a user shuts down SCDF or Skipper the streams definitions page will be blank.
However using the instructions here I am unable to reproduce the base case. What setup would exhibit the behavior. Thanks!

Do the following:

source ./src/deploy/k8s/use-mk-docker.sh mariadb rabbit --snapshot
./src/deploy/k8s/configure-k8s.sh
# minikube tunnel # in separate terminal
./src/deploy/k8s/load-image.sh mariadb:10.6
export NS=scdf
kubectl create namespace "$NS"
kubectl create secret docker-registry registry-key --namespace "$NS" --docker-server=$DOCKER_SERVER --docker-username=$DOCKER_USER --docker-password=$DOCKER_PASSWORD --docker-email=$DOCKER_EMAIL
kubectl patch serviceaccount default -p '{"imagePullSecrets": [{"name": "registry-key"}]}' --namespace "$NS"
kubectl create --namespace $NS -f ./src/kubernetes/mariadb/
kubectl rollout status deployment --namespace "$NS" mariadb

Use k9s to forward mariadb port.
Use IntelliJ Database tools and configure connection to local MariaDB with root/yourpassword

Execute src/main/resources/schemas/mariadb/V1-dataflow.sql

Then execute:

minikube stop
minikube start

Use k9s to forward port on mariadb again.
Check connection and tables in IntelliJ database tools.
