Public bug reported:
Just did a distro upgrade to juno rc2.. Running an old nova-network
cloud with mult-host, nova-api running on compute host. Noticed ubuntu
instances cloud-init is failing:

A bit of poking shows that nova.api.metadata.base.ec2_md_print() is
converting the secgroup list to string:
elif isinstance(data, list):
return '\n'.join(data)
.. but in this case data=[u'default'], and the exception is being raised
when resp.body = u'default'. ec2_md_print() needs to ensure its
returning non-unicode string here.
