Resize glance failing when done before controller-1 configured

[Frank Miller]

Brief Description
-----------------
If a resize of the glance filesystem is done after controller-0 is configured but before controller-1 is configured then the resize fails to occur and services fail to stay enabled after the controller-0 reboot that is done as part of the resize procedure.

Severity
--------
Major: While the resize does work if done when both controller-0 and controller-1 are configured, if a user attempts to resize before controller-1 is configured the system becomes unusable as the services fail to enable.

Steps to Reproduce
------------------
1. install and config controller-0
2. unlock controller-0
3. increase glance storage size
4. after out-of-config is cleared, check glance storage size by 'system storage-usage-list' and 'df -h'

Expected Behavior
------------------
The glance filesystem should change to the new size and all services should go enabled.

Actual Behavior
----------------
The glance filesystem fails to resize and the services (as evidenced by sudo sm-dump command) fail to go enabled.

Reproducibility
---------------
100% reproducible

System Configuration
--------------------
All configurations except for the One Node System.
