Describe the solution you've provided

All Timber events should have one common TAG - LaunchDarklySdk

Describe alternatives you've considered

Just fixing a bug.

Additional context

Timber.tag(<..>) had to be called before logging each event. Previous implementation called tag() once per app lifecycle.

Thanks - we were working on larger changes that would've also included this fix, but it makes sense to do it separately.

One nitpick in terms of Java coding standards: now that this is a method and not a constant/static final field, it should be log(), not LOG().

it should be log(), not LOG().
