Customize default container

MOCO has containers that are automatically added by the system in addition to containers added by the user. (e.g. agent, moco-init etc...)

The MySQLCluster.spec.podTemplate.overwriteContainers field can be used to overwrite such containers. Currently, only container resources can be overwritten. overwriteContainers is only available in MySQLCluster v1beta2.

System containers

The following is a list of system containers used by MOCO. Specifying container names in overwriteContainers that are not listed here will result in an error in API validation.
