          Execute `command` on a remote server. It first calls
          :meth:`Flow.connect_ssh` using all positional and keyword
          arguments, then calls :meth:`SSHClient.execute` with the command
          and pty / echo options.
  
          Args:
              command(str): The command to execute on the remote server.
              arguments...: The options for the SSH connection.
              pty(bool): Request a pseudo-terminal from the server.
              echo(bool): Whether to echo read/written data to stdout by default.
  
          Returns:
              :class:`Flow`: A Flow instance initialised with the SSH channel.
