### Description
Re: Google Cloud Provider -- PubSub

The PubSub [Topics Create API](https://cloud.google.com/pubsub/docs/reference/rest/v1/projects.topics/create#request-body) supports the SchemaSettings and messageRetentionDuration parameters. These should also be supported via the [PubSubCreateTopicOperator](https://github.com/apache/airflow/blob/9207e7d5e5c183d2e63c3030216b14709257668e/airflow/providers/google/cloud/operators/pubsub.py#L50). Thanks!

By default, if the topic already exists, this operator will
    not cause the DAG to fail. ::
        with DAG('successful DAG') as dag:
            (
                PubSubCreateTopicOperator(project_id='my-project', topic='my_new_topic')
                >> PubSubCreateTopicOperator(project_id='my-project', topic='my_new_topic')
            )
    The operator can be configured to fail if the topic already exists. ::
        with DAG('failing DAG') as dag:
            (
                PubSubCreateTopicOperator(project_id='my-project', topic='my_new_topic')
                >> PubSubCreateTopicOperator(
                    project_id='my-project',
                    topic='my_new_topic',
                    fail_if_exists=True,
                )
            )
    Both ``project_id`` and ``topic`` are templated so you can use Jinja templating in their values.
    :param project_id: Optional, the Google Cloud project ID where the topic will be created.
        If set to None or missing, the default project_id from the Google Cloud connection is used.
    :param topic: the topic to create. Do not include the
        full topic path. In other words, instead of
        ``projects/{project}/topics/{topic}``, provide only
        ``{topic}``. (templated)
    :param gcp_conn_id: The connection ID to use connecting to
        Google Cloud.
    :param labels: Client-assigned labels; see
        https://cloud.google.com/pubsub/docs/labels
    :param message_storage_policy: Policy constraining the set
        of Google Cloud regions where messages published to
