Unfortunately, there's none as of now. I found this the hard way that
you cannot trivially find all possible 'extra_spec' key values that can
be set by `nova flavor-key`

I did gross things like this:

    $ grep hw\: nova/virt/hardware.py nova/tests/unit/virt/test_hardware.py | 
sort | uniq

And, obviously the above will only find you 'hw' properties.

Daniel Berrangé once suggested that image properties and flavor extra
specs need to be 'objectified' to alleviate this.
