[Tarantool-patches] [PATCH v4 0/8] lua/log: add an ability to setup logger without box.cfg{}

[Cyrill Gorcunov <gorcunov@gmail.com>]

In the series we add an ability to configure logger early
without calling box.cfg{}. The syntax is the same as
in box.cfg{} call.

There was an idea to implement something similar via triggers but
I think this will require a way more efforts and code redesign,
so at first lets stick to simplier solution.

v2 by Oleg:
 - hide box_api symbols from users
 - initialize logger via log.cfg() call to look similar to box.cfg
v3 by Oleg:
 - add parametesr verification
 - allow to reconfig via log.cfg() call
v4 by Oleg:
 - lua style fixes
 - extent test (I didn't find a way to test wrong params verification
   inside tap test, so I did it manually. Still we might extent the
   test on top of the series).
