Nested tunnel connection will need "sock" instead of "host" configuration.

[lianghwajou]

Will need to use {sock: stream} instead of {host: host} in ssh configuration in order to build a nested tunnel.

ssh2-promise@0.1.2 sshConnections.js

connect(c) {^M this.config = Object.assign(this.config, c);^M ++this.retries;^M if (this.$connectPromise != null)^M return this.$connectPromise;^M this.$connectPromise = new Promise((resolve, reject) => {^M this.emit(sshConstants_1.default.CHANNEL.SSH, sshConstants_1.default.STATUS.BEFORECONNECT);^M

• if (!this.config || typeof this.config === 'function' || !this.config.host || !this.config.username) {^M
• if (!this.config || typeof this.config === 'function' || !(this.config.host || this.config.sock) || !this.config.username) {^M reject("Invalid SSH connection configuration host/username can't be empty");^M this.__$connectPromise = null;^M return;^M }^M
