16.04.2 delayed until Feb 2 for HWE polish

[Adam Conrad]

Due to some parts of the HWE stack still being in flux, the 16.04.2
release will be pushed back to Feb 2.  Don't take that as an excuse
to shove more things in last-minute, but if you did have one or two
critical bugfixes that weren't going to make it in time, it wouldn't
hurt to throw those at the xenial queue ASAP, so we can evaluate if
they might be able to slip in with the rest of the bits.
