Nick Khyl d832467461 client/tailscale,ipn/ipn{local,server},util/syspolicy: implement the AlwaysOn.OverrideWithReason policy setting
In this PR, we update client/tailscale.LocalClient to allow sending requests with an optional X-Tailscale-Reason
header. We then update ipn/ipnserver.{actor,Server} to retrieve this reason, if specified, and use it to determine
whether ipnauth.Disconnect is allowed when the AlwaysOn.OverrideWithReason policy setting is enabled.
For now, we log the reason, along with the profile and OS username, to the backend log.

Finally, we update LocalBackend to remember when a disconnect was permitted and do not reconnect automatically
unless the policy changes.
