[PATCH RFC v2 0/1] the org.qemu.Display1.UIInfo interface design

Currently, the `SetUIInfo` method cannot set a refresh rate.
Simply adding a refresh_rate argument would break the method signature.

This RFC adds the `UIInfo` interface containing
  * properties as staged display settings.
  * the method Apply applying staged settings.
  * the method Reload reloading settings from the console.

This patch needs further discussion on:
  * public API
  * necessary test suite

Changes since v1:
  * redesigned public API

Test results:
  * qemu:qtest-x86_64/dbus-display-test passed
  * qemu:qtest-x86_64/dbus-vmstate-test passed
  * qemu:qtest-x86_64/dbus-vnc-test SKIP
  * manually created a virtual machine
    and successfully set its refresh rate and resolution via `UIInfo`
