### Description
This PR fixes the issue #7999
While putting the storage pool datastore cluster in maintenance mode, then
there are chances that the cloud.uuid gets updated with UUID without hyphens
('-') which causes issue with sync storage pool.
In my case this is happening if there any hosts in the clusters which does
not have access to the storage pool.
In this PR we are making sure that the UUID does not change to uuid without
hyphens

### Screenshots (if appropriate):
Before and after putting the storage pool in maintenance mode, cloud.uuid
has not changed

Before the fix, this UUID has changed to UUID without hyphens
### How Has This Been Tested?
<!-- Please describe in detail how you tested your changes. -->
<!-- Include details of your testing environment, and the tests you ran to
-->
1. Prepare a datastore cluster with 2 child datastores
2. Add datastore cluster as primary storage in CloudStack
3. Put the datastore cluster in maintenance mode or restart management
server (as part of the fix, make sure the cloud.uuid in child storage pool does
not. UUID has to be with hyphens)
4. Add or remove new child datastore in vCenter
5. Try sync storage pool operation on the datastore cluster => succeeded.
