Cache events to allow caching power state and avoid extra API calls. With that, also trust the client to return us the appropriate power state that it set on the event, instead of making derivative tools roll their own state definition. Fixes: QubesOS/qubes-issues#10977 Fixes: QubesOS/qubes-issues#10978 For: QubesOS/qubes-issues#10966 Requires: QubesOS/qubes-core-admin-client#480

"Transient" state will be fully deprecated on Qubes R5.0. For now, "Halting" is received but "Staring" is not received yet. As a bonus, for argument choices, depend on core-admin-client to have the most up-to-date list. For: QubesOS/qubes-issues#10966 Requires: QubesOS/qubes-core-admin-client#480

When checking libvirt event callbacks, VIR_DOMAIN_EVENT_STOPPED is the only event called when shutting down or destroying/killing a domain, so the state transitions from Running->Halted, therefore, never sending "Halting" or "Dying". I checked the clients, and only qubes-manager uses "Dying", but it has a "Halting" equivalent, which all translate to the same visuals as "Transient".
Variables set on the module level so it can be reused by other clients.
Besides the name "Transient" means impermanent, it could as well take a long time in case the qrexec agent on the qube broke. Also it doesn't help anything knowing that via the power state, it should be broadcasted in another manner. It also doesn't tell the clients why it is in a transient state, while "Starting" and "Halting" really does tell us what is happening. On Qubes R5.0, there will be no "Transient" state, it will be fully replaced by "Starting". For: QubesOS/qubes-issues#10964 For: QubesOS/qubes-issues#10966
