Simplify validation while creating volume templates via UI

[hsato03]

Description

Currently, creating templates for DATADISK volumes is only possible if they have already been part of a VM and are detached. This behavior has been extended so that the volume does not need to be detached and the template can be created as long as the VM is stopped.

Furthermore, the UI allows templates to be created for ROOT volumes in the Allocated state, however, the creation always results in an error as the volume needs to exist in the primary storage for the template creation to be possible. With the changes, this option is no longer available.

Types of changes

• Breaking change (fix or feature that would cause existing functionality to change)
• New feature (non-breaking change which adds functionality)
• Bug fix (non-breaking change which fixes an issue)
• Enhancement (improves an existing feature and functionality)
• Cleanup (Code refactoring and cleanup, that may add test cases)
• build/CI
• test (unit or integration test code)

How Has This Been Tested?

In the UI, I tried creating a template from a volume in different scenarios:

N°	VM State	Volume Type	Volume State	Could create the template?
1	Stopped	ROOT	Allocated	No
2	Stopped	ROOT	Ready	Yes
3	Stopped	DATADISK	Ready	Yes
4	Detached volume	DATADISK	Ready	Yes
5	Running	ROOT	Ready	No
6	Running	DATADISK	Ready	No

clgtm (and tested by @Pearl1594 ) not sure what caused the build failures yet, but investigating
