 * {@link liquibase.configuration.ConfigurationValueProvider} that simulates the behavior from pre-4.4 methods like {@link liquibase.configuration.GlobalConfiguration#setOutputEncoding(String)}.
 * It is also useful for integrations that do not yet support a "Scope" style calling of logic.
 * The values set in here should override environmental settings like {@link SystemPropertyValueProvider} but is overridden by new-style code using {@link ScopeValueProvider}.
