在ingress实例注解加入超时配置（默认60s）

metadata:
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/proxy-body-size: 10240m
    nginx.ingress.kubernetes.io/proxy-connect-timeout: "300"
    nginx.ingress.kubernetes.io/proxy-read-timeout: "300"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "300"
