当服务kv不存在时consul_kv的fetch timer会疯狂获取服务数据导致CPU 100%
2021/07/20 07:11:55 [error] 42#42: *193170 [lua] consul_kv.lua:329: connect consul: http://10.242.154.205:8500/v1/kv/ by key: /kv/apisix-service-upstreams, got result: null, with error: timeout, context: ngx.timer
目测是因为_M.connect异常后直接再次跳转到:: ERR ::再次尝试_M.connect~ 死循环了

This is a bug now :))
I would submit a PR later to fix it.
And, if you want to avoid the bug at the moment, you should insert some test data into `/apisix-service-upstreams` key space.

What about using exponential backoff with retry instead of retrying immediately?
We can try after 1,4,16,64,256,256,... seconds.
