StaticFile.fromFile has too many overloads

We abused overloading on StaticFile.fromFile. Look at reducing overloads, either through default parameters or different names for the functions. Deprecation is good if we’re changing public API in a source incompatible way, but if we start now, we can get it cleaned up for 1.0.

Overlaps a bit with #2071, so communicate if you happen to be picking this up at a hack night.

I thought that was something that could be handled by converting to an algebra:

trait Static[F] {
  def calcEtag(file: File): F[String]
  def fromFile(f: File, ..., etagCalculator = calcEtag _): OptionT[F, Response[F]]
}

Yeah, it’s already an effect, so we can get the length and flatMap it.
