crypto: introduce new module for TLS x509 credentials
Introduce a QCryptoTLSCredsX509 class which is used to manage x509 certificate TLS credentials. This will be the preferred credential type offering strong security characteristics Example CLI configuration: $QEMU -object tls-creds-x509,id=tls0,endpoint=server,\ dir=/path/to/creds/dir,verify-peer=yes The 'id' value in the -object args will be used to associate the credentials with the network services. For example, when the VNC server is later converted it would use $QEMU -object tls-creds-x509,id=tls0,.... \ -vnc 127.0.0.1:1,tls-creds=tls0 Signed-off-by: Daniel P. Berrange <berrange@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

+ * This is a user creatable object, which can be instantiated
