util: Add 'usage' for encryption In order to use more common code and set up for a future type, modify the encryption secret to allow the "usage" attribute or the "uuid" attribute to define the secret. The "usage" in the case of a volume secret would be the path to the volume as dictated by the backwards compatibility brought on by virStorageGenerateQcowEncryption where it set up the usage field as the vol->target.path and didn't allow someone to provide it. This carries into virSecretObjListFindByUsageLocked which takes the secret usage attribute value from from the domain disk definition and compares it against the usage type from the secret definition. Since none of the code dealing with qcow/qcow2 encryption secrets uses usage for lookup, it's a mostly cosmetic change. The real usage comes in a future path where the encryption is expanded to be a luks volume and the secret will allow definition of the usage field. This code will make use of the virSecretLookup{Parse|Format}Secret common code. Signed-off-by: John Ferlan <jferlan@redhat.com>
