Public bug reported:

cloud-init runs pollinate via 'cc_seed_random.py' config job.

Some points
a.) in addition to seeding via pollinate seed_random will seed the random device with data from the datasource if it is provided (azure and openstack provide a random seed for this purpose)
b.) we really want seed_random to run before ssh , so that keys are generated with good entropy in place.
c.) seed_random runs early via 'init_modules' mostly to accomplish 'b'.  Unfortunately, network is not guaranteed at this point if the datasource is a 'local' datasource (such as config drive).
e.) in many cases pollinate will not have access to https://entropy.ubuntu.com (due to firewall or disconnected)
f.) in xenial, cloud-init reports events to maas as they occur, and when this module fails, it reports that.
g.) maas marks nodes as failed deployment when cloud-init reports failure

End result, if you dont have access to entropy.ubuntu.com, then you fail
deployment.
