[Feature request] Customize savehist, recentf, places save files locations

[pataquets]

I was trying to customize some file location variables to be in my ~/.spacemacs.d/directory.
Some examples:

• recentf-file-name
• save-hist-file
• save-place-file

Doing it on user-init ended up with the values being overwritten. And doing it on user-config, although somewhat worked, also created files on my .emacs.d dir anyway, adding unnecessary cruft.

I've found the corresponding init-* functions in the spacemacs-defaults layer, which have the directory spacemacs-cache-directory hard-coded, so it looks like to me that it is not possible to do this cleanly. No matter how you approach it, you'll be always working around Spacemacs' logic, which might change in the future.
(As a side note, I wonder if these files belong to the cache dir, but that's another story and it may be just my usage, which is keeping them synchronized between PCs via Dropbox).

If the feature is acceptable and someone is interested into picking this up, what would be the way to expose this?
Adding some dotspacemacs-* variables to be customizable on dotspacemacs/init would be enough?
What would be the recommended naming?
