Fix auto-update to use Lens notifications, and add update confirmation (#1831)

- Add auto-update and pre-release update user settings

- Add settings in user preferences for auto-updating (default false) and
  for allowing pre-release versions (default false)

- Use in-Lens notifications instead of OS notifications as those were
  found to be flaky

- Add rudimentary main->renderer notification system.

- Remove options, always confirm, never auto prelease

- Changed "yes later" to "yes on quit"

- move register IpcHandlers

- use moment instead of dateformat

- moved formatting notification buttons to renderer

- move to RenderButtons as function component

- explicitly only send notifications to main view

- move delay to utils, always retry even if check failed

- fix notification rendering and disabled the auto-updater for integration tests

- update integration runner to output logs on failure

- pin minikube version
