Feature/report play head time

[remyderuiter1]

A new value that is needed in Conviva to get a pass on validation is the playhead time. This can be useful for example in error reporting, to know in what second the user has an issue.

The following changes were made:

• Add new TimeChanged callback for reporting Playhead to conviva playback metric. Calculates Live and Vod playback for reporting.
• Updated conviva-core to 4.0.35

Some tests for ./gradlew ConvivaTestApp:connectedAndroidTest seem to fail. I included the report.
