[openstack-dev] [nova] Removing BDM devices from POST requests

I know we've talked about this over and over and another bug [1] 
reminded me of it. We have long talked about removing the ability to 
specify a block device name when creating a server or attaching a volume 
because we can't honor the requested device name anyway and trying to do 
so just causes issues. That's part of the reason why the libvirt driver 
stopped honoring the block device name in requests back in Liberty [2].

I think we all agree on removing the device name from the API, but I'm 
having a hard time remembering if someone signed up to write a spec for 
this. I could have sworn this came up recently and someone said they'd 
write a spec, but I can't remember.

So this is my attempt at remembering and if it's all a dream, then is 
anyone interested in owning this? If not, I'll start writing the spec 
this week.
