[discuss] retry etcd host in the init_etcd phase when deploy in k8s

[Li Ling(Lien)]

Hello, dev,
recently I am working on installing APISIX via helm chart into K8S with
etcd as dependent.
Due to the  mechanism of  in-house DNS，after the etcd pod is ready，it would
take some time （usually 5~10 seconds）before the internal domain can be
correctly resolved.

here comes two ideas to solve this problem:
1、add a *wait_etcd *phase before init_etcd, to check if the etcd is live or
not.
which means will need to change the code in /bin/apisix
2、change deployment.yaml of helm, add initContainers command to it.

what do you think?
