Update reftable storage repo layout

The change Ic0b974fa (c217d33, "Documentation/technical/reftable:
improve repo layout") defines a new repository layout, which was
agreed with the git-core mailing list.

It addresses the following problems:

* old git clients will not recognize reftable-based repositories, and
  look at encompassing directories.

* Poorly written tools might write directly into
  .git/refs/heads/BRANCH.

Since we consider JGit reftable as experimental (git-core doesn't
support it yet), we have no backward compatibility. If you created a
repository with reftable between mid-Nov 2019 and now, you can do the
following to convert:

  mv .git/refs .git/reftable/tables.list
  git config core.repositoryformatversion 1
  git config extensions.refStorage reftable
