In I5a580fc323c3809790b4a68a9f8f8129ecdc2cf0 we switched off XML support. In
this review we entirely remove all the testcases and supporting files.

`root_gb=0` indicates that a disk-resize shouldn't occur which is not
something that a default flavor should have enabled. This is
especially true of one named 'tiny' since the unresized image could
potentially be very large, leading to the unexpected result of a
'tiny' instance consuming a massive amount of disk.
The no-resize behavior is still supported, so if it's being relied on
for testing, additional, non-default flavors can still be created that
enable it.
