[libvirt] [PATCH v3 4/8] qemu: Refactor hotplug to introduce qemuDomain{Add|Del}TLSObjects

Wed Mar 1 23:30:22 UTC 2017
Refactor the TLS object adding code to make two separate API's that will
handle the add/remove of the "secret" and "tls-creds-x509" objects including
the Enter/Exit monitor commands.
