Both, repair and streaming depend on view builder, but since the builder is started too late, both keep sharded<> reference on it and apply `if (view_builder.local_is_initialized())` safety checks.
However, view builder can do its sharded start much earlier, there's currently nothing that prevents it from doing so. This PR moves view builder start up together with some other of its dependencies, and relaxes the way repair and streaming use their view-builder references, in particular -- removes those ugly initialization checks.
