[Bug 536429] Centralize the full (as much as possible) tracking of release process on 1 single page (like a bugzilla issue)

Description

One time-consuming thing when applying the release process defined by EDP is that the current implementation requires to get to diverse channels to perform this process.
We should try to simplify this by keeping a single source of communication. Something like Bugzilla seems great; so we could track the whole process, including require PMC approval (that typically happen by request on the PMC mailing-list) on the same Bugzilla entry that would give a better overview of the state of the release and what's still to do.
