We decided to make the default value as null to not impact deployments
which didn't specify a NFS version for their secondary storage operations, so
they work as they were before.
About *display* column, we added it to make it consistent with
`ResourceDetail` as we made `ImageStoreDetailVO` implement `ResourceDetail`,
which has the method `isDisplay`.
> Fix for CLOUDSTACK-9252 - Make NFS version changeable in UI

> h3. Introduction
> From [9252|https://issues.apache.org/jira/browse/CLOUDSTACK-9252] it was
> possible to configure NFS version for secondary storage mount.
> However, changing NFS version requires inserting an new detail on
> {{image_store_details}} table, with {{name = 'nfs.version'}} and {{value =
> X}} where X is desired NFS version, and then restarting management server for
> changes to take effect.
> Our improvement aims to make NFS version changeable from UI, instead of
> previously described workflow.
> h3. Proposed solution
> Basically, NFS version is defined as an image store ConfigKey, this implied:
> * Adding a new Config scope: *ImageStore*
> * Make {{ImageStoreDetailsDao}} class to extend {{ResourceDetailsDaoBase}}
> and {{ImageStoreDetailVO}} implement {{ResourceDetail}}
> * Insert {{'display'}} column on {{image_store_details}} table
> * Extending {{ListCfgsCmd}} and {{UpdateCfgCmd}} to support *ImageStore*
> scope, which implied:
> ** Injecting {{ImageStoreDetailsDao}} and {{ImageStoreDao}} on
> {{ConfigurationManagerImpl}} class, on {{cloud-server}} module.
> h4. Important
> It is important to mention that {{ImageStoreDaoImpl}} and
> {{ImageStoreDetailsDaoImpl}} classes were moved from {{cloud-engine-storage}}
> to {{cloud-engine-schema}} module in order to Spring find those beans to
> inject on {{ConfigurationManagerImpl}} in {{cloud-server}} module.
> We had this maven dependencies between modules:
> * {{cloud-server --> cloud-engine-schema}}
> * {{cloud-engine-storage --> cloud-secondary-storage --> cloud-server}}
> As {{ImageStoreDaoImpl}} and {{ImageStoreDetailsDaoImpl}} were defined in
> {{cloud-engine-storage}}, and they needed in {{cloud-server}} module, to be
> injected on {{ConfigurationManagerImpl}}, if we added dependency from
> {{cloud-server}} to {{cloud-engine-storage}} we would introduce a dependency
> cycle. To avoid this cycle, we moved those classes to {{cloud-engine-schema}}
> module
