Title: add out_key_pattern configuration parameter.

I added configuration parameter `out_key_pattern`.
It matches for input records key.

A similar parameter `name_key_pattern` is already exists in fluent-plugin-growthforecast and fluent-plugin-zabbix.
It is useful for handling input records more flexible.
