Backport of python-lockfile and suggested team maintenance

[Andreas Tille <andreas@an3as.eu>]

Hi Ben,

I just uploaded python-lockfile 0.12.2-2~bpo8+1 to backports since I
need it to backport python-schema-salad.

I would have loved to commit the changes to some team Git repository but
you are using a repository outside git.debian.org.  I'd consider it
sensible if you would consider maintaining the package inside DPMT and
the corresponding repository which enables easier contributions to the
package.

Kind regards

      Andreas.
