Goal

Part of AND-864

We now have started publishing Stream Gradle plugins, so I'm doing the initial integration here. Atm they don't do a lot (they just configure the Java version), but I'm building upon this first version to move more and more shared configuration to them.

Implementation

• Replace custom configuration with convention plugins
• Rename video-specific Gradle plugin to have video. in their coordinate, to avoid clashing with generic ones

🎨 UI Changes

None

Testing

Verify that the project & tests build and run as usual.
