tracking progress of "action" API calls

[smira]

Feature Request

In the talosctl CLI track progress of the operations:

• reboot
• reset
• shutdown
• upgrade

.. make the UX better by providing the progress of the operation (10% done, failed, etc.), tracking the progress over the reboot as well (if possible) by waiting for the API to be available after an upgrade.

Tracking progress is the default behavior.

Additional flags:

• --no-wait to restore current fire-and-forget behaviour
• --debug to stream dmesg from the involved nodes for debugging issues

(NB: this should work with multiple --nodes).

Description

Idea: for upgrade, apply-config (in reboot mode) and reboot we should wait for the node to reboot and come back.

• we can use Events API to track the progress
• apid should be kept running as long as possible, possibly it should have a chance to flush the data before stopping
• we can add actor ID to the sequence runner and that gets embedded into the event
• these API calls should return actor ID to the client so that client can filter out events on actor ID
