+ When a vendor data json provides a dictionary without a 'cloud-init'

cloud-init misbehaves when a vendor data json comes with information
that won't be consumed by it, a fix was added in rev 1013[0]. I
backported this patch to Trusty and prepared a patched image, having a
custom vendor data doesn't break cloud-init functionality.
I'll submit a SRU to fix this in Tr
A vendor data file should be a dict with a cloud-init key and the value
for that key is expected to be a string or a list[0], the docs provide a
simple example[1]
Here is another example that will add a user called cloudy, upgrade the
system and install htop:
{"cloud-init": "#cloud-config\nusers:
Changing the class to return a string rather than a dictionary avoids
the cloud-init explosion. That runs counter to all the documentation
that says "use JSON", but it's the workaround we'll use for now
(serializing to YAML).

Screwed up the above script, it should be
from nova.api.metadata import base
class CustomVendordata(base.VendorDataDriver):
def __init__(self, *args, **kwargs):
super(CustomVendordata, self).__init__(*args, **kwargs)
def get(self):
return {"msg": "", "uuid": "4996e2b67d29
Just doing something simple like
data = str(util.decomp_gzip(raw_data))
causes it to work, because data's now a string and hashable and so the
range data[0:4096] works (whether the content is actually what it's
supposed to be is another question).

I can reliably reproduce this issue via the following steps:
1) Create blah.py under nova/api/metadata/ with these contents:
from nova.api.metadata import base

def __init__(self, *args, **kwargs):
super(BcpcMetadata, self).__init__(*args
