Presenter that responsible to create a ImageView and bind to DetailsOverviewRow. The default
implementation uses getImageDrawable() and binds to ImageView.
Default implementation assumes no scaleType on ImageView and uses intrinsic width and height of
getImageDrawable() to initialize ImageView's layout params. To
specify a fixed size and/or specify a scapeType, subclass should change ImageView's layout params
and scaleType in onCreateView(ViewGroup).
Subclass may override and has its own image view. Subclass may also download image from URL
instead of using getImageDrawable(). It's subclass's responsibility to
call notifyOnBindLogo(FullWidthDetailsOverviewRowPresenter.ViewHolder)
whenever isBoundToImage(ViewHolder, DetailsOverviewRow) turned to true so that activity
transition can be started.
