Kernel and ramdisk image ID's are stored for each node profile in nova keys and should be managed via UI. Only image ID is displayed in node profile list. Though somewhat unfriendly, this is better for now than making 2 calls to Glance for every row. Separate node details page will be introduced in the next patch to fix this issue. Also this patch introduce abstraction over flavor to ease writing code specific to node profiles. Change-Id: Ie76651536e2d8b90e14c9000da0226743db91e88
