As a user, I want to avoid specifying all the options for enabling TLS

[apietroni51]

In ClientParams, ssl should be optional, or boolean as a shortcut. All SSLConnectionParams fields should be optional as supported by tls.connect()

export interface SSLConnectionParams {
  key?: string
  cert?: string
  ca?: string
  rejectUnauthorized?: boolean
}

Pseudocode for the socket creation:

private createSocket() {
    const socket = this.params.ssl
      ? tls.connect(this.params.port, this.params.hostname, typeof this.params.ssl === Boolean ? {} : this.params.ssl)
      : new Socket().connect(this.params.port, this.params.hostname)
    if (this.params.socketTimeout) socket.setTimeout(this.params.socketTimeout)
    return socket
}

This will also address #254
