Move VideoConfigService tests near the app

In the test cases we are migrating we are actually testing the functionality of VideoConfigService.

It felt required while shifting test_video.py test case from edx-platform to xblocks-contrib
openedx/xblocks-contrib#144

@farhan Just a question for more context, as per my understanding these tests are for testing videos with multiple or no transcripts translation retrieval. Why we need to move them into new class test_service?

Actually, these are very old tests written before VideoConfigService existed.
We are actually testing the available_translations method which has been moved to VideoConfigService here

@farhan Thanks for the elaborating, why we are making a separate class to move these tests? As tests are already using service to reach these methods.

We are moving test_video.py test to xblocks-contrib, PR shared in the description. Tests belong to VideoConfigService are not suppose to move into the xblocks-contrib. We will eventually remove test_video.py from the edx-platform

LGTM please merge once tests are completed.
