[libvirt] [PATCH 5/7] qemu: Change protocol parameter for secret setup
John Ferlan

Thu Jun 16 11:08:18 UTC 2016
Rather than assume/pass the protocol to the qemuDomainSecretPlainSetup
and qemuDomainSecretAESSetup, determine and pass the secretUsageType
which is then used in the virSecretGetSecretString call
For the two callers that convert from virStorageNetProtocol, add
a new helper qemuDomainSecretProtocolGetUsageType.
