Metrics that could not be retrieved depending on the MySQL version are now retrievable

In mackerel-agent-plugins v0.68.0, mackerel-plugin-mysql was fixed to be able to retrieve metrics that could not be retrieved due to differences between MySQL versions.

The fixes are as follows

• In MySQL 5.7, the format of InnoDB status information was modified and the pending log flushes line that could not be retrieved can now be parsed.
• Fixed a bug in MySQL 5.6, MySQL 5.7 and MySQL 8.0 that prevented getting the asynchronous IO status of InnoDB.
