Support for api-config-gracefulreload

[markosiira-arm]

Tested the fluentd gracefulReload option (https://docs.fluentd.org/deployment/rpc#api-config-gracefulreload) and seems it does not work with this plugin. I get error

2020-04-23 08:17:05 +0000 [error]: Failed to reload config file: Unreloadable plugin plugin: detect_exceptions, plugin_id: object:3fbbc7173e24, class_name: Fluent::DetectExceptionsOutput)

We are using the latest version of the plugin 0.0.13 with Fluentd v1.10.2
