[PATCH v2] box: add on_schema_init trigger

[Konstantin Osipov]

* Serge Petrenko <sergepetrenko at tarantool.org> [19/03/05 18:57]:
> This patch introduces an on_schema_init trigger. The trigger may be set
> before box.cfg() is called and is called during box.cfg() right after
> prototypes of system spaces, such as _space, are created. This allows to
> set triggers on system spaces before any other non-system data is
> recovered. For example, it is possible to set an on_replace trigger on
> _space, which will work even during recovery.

Now lgtm, Vova, please do your own review and push.
