https://bugzilla.redhat.com/show_bug.cgi?id=1300776 Complete the implementation of support for TLS encryption on chardev TCP transports by adding the hotplug ability of a secret to generate the passwordid for the TLS object for chrdev, RNG, and redirdev. Fix up the order of object removal on failure to be the inverse of the attempted attach (for redirdev, chr, rng) - for each the tls object was being removed before the chardev backend. Likewise, add the ability to hot unplug that secret object as well and be sure the order of unplug matches that inverse order of plug. Signed-off-by: John Ferlan <jferlan@redhat.com>
