plugins: Wire up python plugin support for NBD_INFO_INIT_STATE
The NBD protocol is adding an extension to let servers advertise
initialization state to the client: whether the image contains holes,
and whether it is known to read as all zeroes. For python, the
hardest part was figuring out how to conditionally test things
depending on new-enough libnbd (and that wasn't hard).
Note that the python bindings do not yet support extents, so this is
one case where the new protocol addition is definitely useful when
dealing with an initially-empty destination.
