[libvirt] [PATCH v4 21/42] secret: introduce virtsecretd daemon

[Daniel P. Berrangé]

The virtsecretd daemon will be responsible for providing the secret API
driver functionality. The secret driver is still loaded by the main
libvirtd daemon at this stage, so virtsecretd must not be running at
the same time.
