"""
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:
Whatever the operation.result() 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.

Creates a copy of another image.
Args:

source_image_name: name of the image you want to copy.
image_name: name of the image you want to create.
source_project_id: name of the project that hosts the source image. If left unset, it's assumed to equal
the `project_id`.
guest_os_features: an iterable collection of guest features you want to enable for the bootable image.
Learn more about Guest OS features here:
https://cloud.google.com/compute/docs/images/create-delete-deprecate-private-images#guest-os-features
storage_location: the storage location of your image. For example, specify "us" to store the image in the
`us` multi-region, or "us-central1" to store it in the `us-central1` region. If you do not make a selection,
Compute Engine stores the image in the multi-region closest to your image's source location.
Returns:
An Image object.
