[users at bb.net] Deleting old buildmasters

[Pierre Tardy]

Hi Linus,

There is not yet official way to cleanup old masters.
Buildbot 0.9.7 introduced the Janitor for that purpose, which for now only
clean's up old logs.
The idea is that we should implement cleanup for the other data over time.
Any help will be greatly appreciated to implement the remaining bits.

Pierre
