5c237a07dc refactor(metrics): make to_text get the application state 
As falco may update its state at any time and thus its inspectors objects,
keeping pointers to them may end up in using dangling values.

Therefore, use the state of the application when requesting metrics.

Optimizations such as caching of mostly static values will be done in
a follow up patch.

05e796723f fix(userspace): remove unread variable in restart_handler

leaves the loop, hence setting should_restart as false makes no sense
in this context.
