[PATCH 0/4] Introduce a new virDomainReloadTlsCertificates API

[Zheng Yan]

The new virDomainReloadTlsCertificates API is used to notify domain reload
its certificates without restart, and avoid service interruption.

Currently, only QEMU VNC TLS certificates are supported, but parameters and
flags are also reserved for subsequent scenarios.

Take reload QEMU VNC TLS certificates as an example, we can call:

  virDomainReloadTlsCertificates(domain,
                                 VIR_DOMAIN_TLS_CERT_GRAPHICS_VNC,
                                 NULL, 0, 0);

Then the specified QMP message would be send to QEMU:
{"execute": "display-reload", "arguments":{"type": "vnc", "tls-certs": true}}

This is v3 patch, thanks for Han Han and Michal previous review.
