Functionally this patch looks fine, but having tried it out I'm wondering
about the 'secret-list' command output...

eg, i defined 6 secrets, and now the listing shows.
# ./src/virsh secret-list
UUID
-----------------------------------------
1b4fde6f-0929-3bb5-c2aa-0f62ef79e52a
3174ee25-1be0-ba8f-1c99-d0b929226d7e

which isn't very user friendly. I think we need to try and get info
about the usage of the secret included in the output,
eg consider if we allowed use of the secrets API for managing per
guest secrets for the VNC server too, then I could imagine a
display like
# ./src/virsh secret-list
UUID Usage Object
----------------------------------------------------
1b4fde6f-0929-3bb5-c2aa-0f62ef79e52a volume /var/lib/libvirt/images/demo.img
3174ee25-1be0-ba8f-1c99-d0b929226d7e volume /var/lib/libvirt/images/mail.img

This might suggest that we have 1 or 2 more public APIs,
const char *virSecretGetUsage(virSecretPtr sec);
const char *virSecretGetObject(virSecretPtr sec);
and, probably that we include those 2 attributes in the virSecretPtr
struct defined in src/datatypes.h, so that calling those 2 APis does
not incur further RPC calls. This would also mean that we'd have to
extend
struct remote_nonnull_secret {
remote_nonnull_string uuid;
};
to include
struct remote_nonnull_secret {
remote_nonnull_string uuid;
remote_nonnull_string usage;
remote_nonnull_string object;
};
