confd的配置

confd.toml为confd服务本身的配置文件，主要记录了使用的存储后端、协议、confdir等参数。
/etc/confd/confd.toml by default
存储后端nacos配置：

backend = "nacos"
confdir = "/etc/confd"
#log-level = "debug"
interval = 5
nodes = [
  "http://192.168.1.101:8848",
]
scheme = "http"
watch = true

创建confdir

confdir底下包含两个目录:

conf.d:confd的配置文件，主要包含配置的生成逻辑，例如模板源，后端存储对应的keys，命令执行等。
templates:配置模板Template，即基于不同组件的配置，修改为符合 Golang text templates的模板文件。
