Converting ENUMS to str can be user friendly though
it can be problematic in matters of backward compatibility.
In particular when some ENUM in libvirt API will introduce a
new constant, libvirt-dbus will fail with:
size of array ‘_GStaticAssertCompileTimeAssertion_5’ is negative
So using ints is preferable to avoid the previous issue.
