**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.

"""
    Create a new cluster on Google Cloud Dataproc. The operator will wait until the
    creation is successful or an error occurs in the creation process. If the cluster
    already exists and ``use_if_exists`` is True then the operator will:
    - if cluster state is ERROR then delete it if specified and raise error
    - if cluster state is CREATING wait for it and then check for ERROR state
    - if cluster state is DELETING wait for it and then create new cluster
    Please refer to
    https://cloud.google.com/dataproc/docs/reference/rest/v1/projects.regions.clusters
    for a detailed explanation on the different parameters. Most of the configuration
    parameters detailed in the link are available as a parameter to this operator.
