[nova]: Separation of VM size and extra specs in flavors

Hi,

During some discussions about CNTThttps://cntt.readthedocs.io/, where several flavor sizes and extra specs are specified we realized, that the combination of all flavor sizes and the different extra specs results in a very large number of flavors.

One idea was to separate the size and the extra specs on the creation of flavors and just define some kind of rules do define how the different sizes and extra specs can be combined. The other idea was just to leave things as they are.

Are there any opinions on which idea is better?

Thanks, Gerg0
