Waits for the extended (long-running) operation to complete.
If the operation is successful, it will return its result.
If the operation ends with an error, an exception will be raised.
If there were any warnings during the execution of the operation
they will be printed to sys.stderr.
Args:
operation: a long-running operation you want to wait on.
verbose_name: (optional) a more verbose name of the operation,
used only during error and warning reporting.
timeout: how long (in seconds) to wait for operation to finish.
If None, wait indefinitely.
Returns:

Raises:
This method will raise the exception received from `operation.exception()`
or RuntimeError if there is no exception set, but there is an `error_code`
set for the `operation`.
In case of an operation taking longer than `timeout` seconds to complete,
a `concurrent.futures.TimeoutError` will be raised.
