The 'display-reload' QMP command had been introduced from QEMU 6.0.0:
https://gitlab.com/qemu-project/qemu/-/commit/9cc07651655ee86eca41059f5ea...
TO support the new QMP command, we added a new internal API
'virDrvDomainReloadTlsCertificates' to virHypervisorDriver, and
implemented the qemu driver.
Only QEMU VNC TLS certificates are supported currenly.
