Change in ovirt-engine[master]: core: Extract SD validations from ImagesHandler

Allon Mureinik has submitted this change and it was merged. Change subject: core: Extract SD validations from ImagesHandler ...................................................................... core: Extract SD validations from ImagesHandler Extracted the logic to perform validations on Storage Domains from ImagesHandler.PerformImagesChecks, and made the relevant commands use it directly. In order to do this, a new type of validator was introduced, MultipleStorageDomainsValidator, which aggregates validations from individual StorageDomainValidators in a fast-fail pattern. This is done for performance reasons, so there is no need to load all the storage domains from the database preemptively. This refactoring removes three parameters from PerformImagesChecks: * checkStorageDomain and diskSpaceCheck - are now done directly by MultipleStorageDomainsValidator. * storageDomainId - is used by the previous two checks, and by the image existence check. However, it is always equal to the storage domain id member of the DiskImage, so it is redundant as an additional parameter. The changes in the commands are as follows: * The parameters detailed above were removed from the ImagesHandler.PerformImagesCheck calls. * Wherever appropriate, a direct call to StorageDomainValidator or MultipleStorageDomainsValidator was added.
