配置grafana

Remove grafana provisioning config删除grafana配置文件(/etc/grafana/provisioning/dashboards/pigsty.yml和/etc/grafana/provisioning/datasources/pigsty.yml)
Remake grafana resource dir重做grafana资源文件夹（/etc/grafana/、/etc/dashboards、/etc/grafana/provisioning/dashboards、/etc/grafana/provisioning/datasources）
Templating /etc/grafana/grafana.ini、Templating datasources provisioning config、Templating dashboards provisioning config模板化配置文件（grafana.ini、datasources-pigsty.yml、dashboards-pigsty.yml）

启动

Launch grafana service使用systemd模块启动grafana-server，使用wait_for模块等待grafana上线

Provisioning

Sync grafana home and core dashboards同步所有的dashboards到/etc/pigsty/dashboards/
Provisioning grafana with grafana.py调用shell模块export相关变量，并执行 /etc/pigsty/dashboards/grafana.py init /etc/pigsty/dashboards/

注册Grafana Service

Register Grafana Service调用template模块模板化svc-grafana.json.j2到目标配置文件/etc/consul.d/svc-grafana.json
Reload consul重载Reload consul，使用systemd模块
