apisix/t/certs/etcd.key

feat: support TLS connection with etcd. (#2548) Support the TLS connection when communicating with etcd cluster. We added a configuration item to custom the certificate verification. Whether to setup TLS connection or not depends on the endpoints' scheme, for instance, when endpoints are: ``` etcd: host: - "https://127.0.0.1:2379" - "https://127.0.0.1:3379" ``` APISIX will originate TLS connection automatically, and the Server Name Indication extention will be set by the endpoint host (`127.0.0.1` in above case). Note by default APISIX will verify the certificate, close the verification in configuration explicitly if you want to bypass it. ``` etcd: tls: verfiy: false ``` 2020-11-03 13:53:39 +08:00			`-----BEGIN PRIVATE KEY-----`
