This commit makes isOutdated validate a nodes necessity to update
against all namespaces, and not just the nodes own namespace (which made
more sense before).
getLastStateChange is now uses the passed namespaces as a filter,
meaning that not requesting any namespace will give you the total last
updated state.
In addition, the sync.Map is exchanged for a variant that uses generics
which allows us to remove some casting logic.
This commit removes the need for datatypes.JSON and makes the code a bit
cleaner by allowing us to use proper types throughout the code when it
comes to hostinfo and other datatypes on the machine object.
This allows us to remove alot of unmarshal/marshal operations and remove
a lot of obsolete error checks.
This following commits will clean away a lot of untyped data and
uneccessary error checks.
This commit adds some Prometheus metrics to /metrics in headscale.
It will add the standard go metrics, some automatic gin metrics and some
initial headscale specific ones.
Some of them has been added to aid debugging #97 (loop bug)
In the future, we can use the metrics to get rid of the sleep in the
integration tests by checking that our expected number of nodes has been
registered:
```
headscale_machine_registrations_total
```
This code adds new http handlers that will generate iOS and macOS
configuration profiles allowing us to override the Control server of the
official Tailscale.app.
Currently, macOS is working, as I have not found the correct "key" to
inject for iOS.
This means that a profile will allow users to no longer log in via the
command line, but they can use the app.
