Problem: As reporeted in fsouza#667. The storage API is replying 404 for existing objects when method HEAD is used, although GET replies with 200. Solution: Update storage API method route and handler to behave as "donwload" when HEAD method is used.
Problem: As a new user, one tends to simply use what comes in the README.md file without realizing there is plenty more features at hand. Solution: Update README.md to pointing out there is a -help flag that lists all the available configuration overrides. I was tempted to copy and paste its output, but it might add too much noise for the reader so disregarded that thought.

Oh I didn't realize this supported HEAD 🤔
We should probably rename this method, but doesn't need to be as part of this PR.

Yeah, I had a similar thought, either renaming this function with another verb or splitting its functionality. However, I picked the route with less changes 😅

I think I found a easy way to fix #667.
I also took the liberty to update the documentation, spelling out the
-helpflag usage for new users. Fun story, when I started using this emulator, I jumped into the code to figure out if there was a way to support my use case; I went from the endpoints to the handler implementation. Lastly, I found out all that the flags definitions were sitting inconfig.gofile, also that I could simply have used said flag all the time 😅.Both changes are in separted commits in case we want to drop or modify any of them.
