ArrayNodeDefinition::canBeEnabled()

Adds an "enabled" boolean to enable the current section.

By default, the section is disabled. If any configuration is specified then the node will be automatically enabled:

enableableArrayNode: {enabled: true, ...} # The config is enabled & default values get overridden enableableArrayNode: ~ # The config is enabled & use the default values enableableArrayNode: true # The config is enabled & use the default values enableableArrayNode: {other: value, ...} # The config is enabled & default values get overridden enableableArrayNode: {enabled: false, ...} # The config is disabled enableableArrayNode: false # The config is disabled
