cipher-suites not honored from configuration file

[petersutty]

I am trying to configure ciphers from etcd configuration file, but its not accepted by etcd

config file:
name: infra0
initial-advertise-peer-urls: https://infra0.syspay.com:2380
listen-peer-urls: https://10.0.1.10:2380
listen-client-urls: http://127.0.0.1:2379
advertise-client-urls: http://127.0.0.1:2379
initial-cluster-token: etcd-cluster-1
initial-cluster: infra0=https://10.0.1.10:2380,infra1=https://10.0.1.11:2380,infra2=https://10.0.1.12:2380

cipher-suites: TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
logger: zap

log:

etcd version:
etcd Version: 3.4.3

another docs issue:
if you go https://etcd.io/docs/v3.4.0/op-guide/configuration/ and click on "sample configuration file" - https://etcd.io/docs/v3.4.0/etcd.conf.yml.sample is missing
