Support upload Templates where the format is compressed

### The required feature described as a wish

As a User/Admin/Operator I would like to upload a compressed template from local

Currently Cloudstack supports the registration of template whose format is also compressed

resolute-server-cloudimg-amd64.img
resolute-server-cloudimg-amd64.qcow2
resolute-server-cloudimg-amd64.qcow2.bz2
resolute-server-cloudimg-amd64.xz

When a admin user tries to upload a template from local whose format is .qcow2.bz2 it fails

resolute-server-cloudimg-amd64.qcow2.bz2
resolute-server-cloudimg-amd64.tar.gz
resolute-server-cloudimg-amd64-root.tar.xz

Error is thrown

Comienza por la ruta de carga de plantillas local y el error de UploadStatusCheck indicado; después, sigue el recorrido hasta el punto donde se compara el tipo de archivo cargado con el formato QCOW2 seleccionado. Se considera terminado cuando las cargas locales de los formatos comprimidos enumerados, incluidos .qcow2.bz2, .tar.gz y .root.tar.xz, ya no fallen por una discrepancia de tipo de archivo.
