升级grafana

We recommend everyone to upgrade Grafana often to stay up to date with the latest fixes and enhancements. In order make this a reality Grafana upgrades are backward compatible and the upgrade process is simple & quick.

grafana官方建议保持持续升级至最新修复版，因为grafana只是作为展示层，升级对程序打点和数据收集无影响，而且grafana是后向兼容的，升级只会影响监控的查看和报警。

大版本升级注意事项：大版本升级跨度太大可能会导致问题出现，升级中选择小版本逐个升级，如在v5.x 升级至v6.x没有任何报错，都可正常运行访问。当升级v7.x之后的版本面临数据库报错。
