This roughly turned out to be correct :)

In short, we now have ready xenial arm64 based nodes.  If you request
an ubuntu-xenial-arm64 node it should "just work"

There are some caveats:

 - I have manually installed a diskimage-builder with the changes from
   [1] downwards onto nb03.openstack.org.  These need to be finalised
   and a release tagged before we can remove nb03 from the emergency
   file (just means, don't run puppet on it).  Reviews welcome!

 - I want to merge [2] and related changes to expose the image build
   logs, and also the webapp end-points so we can monitor active
   nodes, etc.  It will take some baby-sitting so I plan on doing this
   next week.

 - We have mirror.cn1.linaro.openstack.org, but it's not mirroring
   anything that useful for arm64.  We need to sort out mirroring of
   ubuntu ports, maybe some wheel builds, etc.

 - There's currently capacity for 8 nodes.  So please take that into
   account when adding jobs.

Everything seems in good shape at the moment.  For posterity, here is
the first ever arm64 ready node:

 nodepool at nl03:/var/log/nodepool$ nodepool list | grep arm64
 | 0002683657 | linaro-cn1 | ubuntu-xenial-arm64 | c7bb6da6-52e5-4aab-88f1-ec0f1b392a0c | 211.148.24.200  |                                        | ready    | 00:00:03:43 | unlocked |
