**Description**
Currently, we can only pass custom Image name to  **DataprocClusterCreateOperator(),**
as the custom image expires after 60 days, we either need to update the image or we need to pass the expiration token.

Functionality is already available in **gcloud** and **REST**.

`gcloud dataproc clusters test_cluster ......
--image projects/<custom_image_project_id>/global/images/family/<family_name>
.......
`


**Use case / motivation**
The user should be able to pass either Custom Image or Custom Image family name,
so we don't have to update the image up on expiration or use expiration token.
