Title:
No need to backup instance when 'rotation' equals to 0
Status in OpenStack Compute (Nova):
Opinion
Bug description:
Nova will delete all backup images according the 'backup_type'
parameter when 'rotation' equals to 0.
But according the logic now, Nova will generate one new backup, and
then delete it..
So It's weird to snapshot a useless backup firstly IMO.
We need to add one new branch here: if 'rotation' is equal to 0, no need to
backup, just rotate it.
