Gerrit

From the ESC minutes:

We discussed whether the ESC should always be involved in the review of
design documents. The conclusion was that it's not always necessary; it depends
on the proposed feature and whether there are concerns/questions raised in the
review that require escalation. However, it was proposed that at least one
member of the ESC should be involved in the review to ensure that it progresses
and does not get stale.

It was also suggested that we should encourage people to send an email to the
project mailing list when a new design is uploaded, however this should not be
a mandatory step. We should also be careful to keep the discussion of the
design in the review on Gerrit rather than in the mail thread.
