Reduce the use of the term `long-term`, when what we're really talking
about is remote clustered storage for increased capacity and durability.

As discussed generally consider SDs as unstable, as realistically they
are never going to be. Drop the words "experimental/beta" from most
places in the docs, as users are getting the wrong impression from this.
The only section that still aplies was the one on the default storage
directory so those docs seem obsolete.
We'll probably have a similar page on the new storage but we'll only
find out what caveats etc. we'll have to point out as we get people
reporting problems or notable behavior.
