Title:
Cloud-init causes potentially huge boot delays with 4.15 kernels

Bug description:
Newer 4.15 kernels contain the following fix for CVE-2018-1108:
43838a23a05fb ("random: fix crng_ready() test")
This causes cloud-init to stall for a potentially long time during
boot (waiting for entropy I presume). Google reported boot delays of
75 minutes.
I've tracked this down to the following import in templater.py which causes
the delay:
from jinja2 import Template as JTemplate
Which is called when cc_update_etc_hosts is imported.
