Bug Description

I've observed that immediately following a revert resize, the API returns the flavor the server was resizing to, not the original flavor. For example, if I resize a server with flavor 1 and I resize to flavor 2, but then decide to revert, after returning to the ACTIVE status, a GET request for that server may return the incorrect flavor for 1-10 seconds afterwards.

One of the Tempest tests (test_resize_server_revert in test_server_actions.py) can reproduce this issue.

My two patches add a new REVERT_RESIZE state to make it clear to the client what is going on.
