Public bug reported:

Description
===========
user-data not getting updated when the instance is rebuilt using the snapshot taken from the same instance

Steps to reproduce
==================
1. create an instance with the user-data
openstack server rebuild --image c2022d1d-5549-46f1-b220-810019ae7d5e --user-data user_data.txt 5b75696f-1f8a-45ea-ac8e-12b4988cb2d4 --os-compute-api-version=2.57
2. login to instance and check user-data
3. create a snapshot
openstack server image create --name snapshot1 5b75696f-1f8a-45ea-ac8e-12b4988cb2d4
4. rebuild the server with the snapshot and a different user-data
openstack server rebuild --image c2022d1d-5549-46f1-b220-810019ae7d5e --user-data user_data_new.txt 5b75696f-1f8a-45ea-ac8e-12b4988cb2d4 --os-compute-api-version=2.57
5. login to the instance and check user-data. the user-data passed during the rebuild is not present in /var/lib/cloud/instnace/user-data.txt. Its the old user-data which is passed during the instance creation

Expected result
===============
the user-data passed during the rebuild should be applied

Actual result
=============
user-data passed during rebuid is not getting applied

Environment
===========
$ rpm -qa | grep nova
