FIELD_CONFIG_VERSION = 'configVersion'
$configurationDefinitions : \Symfony\Component\Config\Definition\ConfigurationInterface[]
processConfiguration(array $values) : array
Normalizes and validates the given values.
When this version of the configuration can be upgraded (which is detected by the Upgradable interface on the Configuration definition) then it will do so and re-run this method with the upgraded values. The 'configVersion' field will tell which definition should be used; when none is provided then a version 2 configuration is assumed.
