Add options to Put, PutUnchecked and Update, add HashOption and speed up local

* Add options to Put, PutUnchecked and Update for all Fses
  * Use these to create HashOption
  * Implement this in local
  * Pass the option in fs.Copy

This has the effect that we only calculate hashes we need to in the
local Fs which speeds up transfers significantly.
