Make config_feature_flag's default_value optional. With this change, if the default_value is not set, but the flag has been given a value by a configuration transition, that value is used and no error is produced. If the default_value is not set and the flag has not been given a value by a configuration transition, the rule produces an error (as it did before, but now the error is different). config_feature_flags with default_values behave as they did before. (use the default value if no configured value is set, otherwise use the configured value) Also transition the Optional used in feature flags from Guava to Java 8. RELNOTES: config_feature_flag's default_value is optional. It is only an error to have a config_feature_flag with no default_value if that config_feature_flag has not been set in the configuration it is being evaluated in. PiperOrigin-RevId: 178418907
