    CLOUDSTACK-9438: Fix for CLOUDSTACK-9252 - Make NFS version changeable in UI

    ### Introduction
    From #1361 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
    ### 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.
    ### 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 `ImageStoreDetailsDao` 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
