🍼 init

• Avoid hacking with bash initContainers, do it properly in Go
• Dynamically provision MariaDB Galera configuration file
• Get MariaDB resources from the Kubernetes API and configure Galera based on them
• Guarantee MariaDB ordered deployment by checking its Pod Ready conditions in the Kubernetes API
• Allow spec.podManagementPolicy = Parallel in the MariaDB StatefulSet
