Method to set default quality set for VOD and Live transcoding.

For changing default quality set, specify the ID of the custom quality set from the method GET /quality_sets.

Default value can be reverted to the system defaults (cleared) by setting "id": null.

Live transcoding management:

• You can specify quality set explicitly in POST /streams method, look at attribute "quality_set_id".
• Otherwise these default values will be used by the system by default.

VOD transcoding management:

• You can specify quality set explicitly in POST /videos method, look at attribute "quality_set_id".
• Otherwise these default values will be used by the system by default.
