micro release exception for bzr

[Martin Pool]

Thanks, everyone.  Since there do not seem to be any objections, would
one of you please add bzr to
<https://wiki.ubuntu.com/StableReleaseUpdates/MicroReleaseExceptions>?

I infer that even after we're added, we should keep nominating
figurehead bugs to kick off each individual SRU?

I think it's worth giving it a go, because we have fixed a good number
of timing or environment-dependency test suite bugs.  Perhaps I should
propose a change in Natty that turns it back on?
