Created fluent-plugin-sqlite3 for my training

fluentd is a cool product so I try it for my biz.

In the case I use it, I have to write some plugins of fluentd. For now, as a training, I wrote a small plugin for sqlite3.

https://github.com/tmtk75/fluent-plugin-sqlite3

I added ad hoc mode. It doesn't need you define schema. It creates tables based on a JSON you sent. I think you casully start to try this plugin.

Adding a plugin was easier than I've thought. fluentd is nice!
