**Apache Airflow version**: 1.10.12

**Environment**:  Google Cloud Composer 1.13.3

- **Cloud provider or hardware configuration**:
- Google Cloud Composer

**What happened**:
The GoogleDisplayVideo360Hook.download_media hook tries to download media using the "resource_name" argument. However, [per the API spec](https://developers.google.com/display-video/api/reference/rest/v1/media/download) it should pass "resourceName" Thus, it breaks every time and can never download media.

Error: `ERROR - Got an unexpected keyword argument "resource_name"`

**What you expected to happen**: The hook should pass in the correct resourceName and then download the media file.


**How to reproduce it**: Run any workflow that tries to download any DV360 media.

**Anything else we need to know**: I have written a patch that fixes the issue and will submit it shortly.
