This change does a few things:
1. Moves the post-condition paragraph into an
"Asynchronous Postconditions" section like other
API references.
2. Drops the "RESIZED" VM status wording since what
that probably meant was the server OS-EXT-STS:vm_state
value would be "resized" but what was in the reference
was (a) wrong and (b) redundant with the VERIFY_RESIZE
status.
3. Re-words and links the resize_confirm_window config
option wording since saying "if you set" a config option
in the API reference does not really make sense since
"you" (the non-admin cloud user) does not have control
over how the cloud is configured.
