Contacting maintainers about no-dsa

[Sylvain Beucler <beuc@beuc.net>]

Hi,

At the wiki process page we say:
https://wiki.debian.org/LTS/Development#Contact_the_maintainer
  When we tag issues as "no-dsa", and don't plan to take care of the
updates by ourselves, then we use it in this way:
  $ bin/contact-maintainers --lts --no-dsa sudo CVE-2014-9680 CVE-2014-0106

I was about do contact the nettle and gnutls maintainers, but after
discussing with Emilio on IRC it appears that we do not contact
maintainers for this anymore.

Should we delete the section?

(incidentally I fixed the remaining wheezy references in the template)

Cheers!
Sylvain
