Directly include RequestOptions in ReqestBuilder using CRGP

https://www.artima.com/weblogs/viewpost.jsp?thread=133275

This means that you can write:

Glide.with(context)
  .load(url)
  .placeholder(R.drawable.placeholder)
  .into(imageView);

Instead of:

Glide.with(contex)
  .apply(placeholderOf(R.drawable.placeholder)
  .into(imageView);

Without using the generated API.
