[libvirt] [PATCH 12/14] secret: Introduce secretAssignDef

[John Ferlan]

This new API will allocate the secret, assign the def pointer, and
insert the secret onto the passed list. Whether that's the temporary
list in loadSecrets which gets loaded into the driver list or driver
list during secretDefineXML.
