https://github.com/tarantool/tarantool/issues/4398
https://github.com/tarantool/tarantool/tree/lvasiliev/gh-4398-expose-error-module

The first part of the expose box.error task includes:
1) Lua backtrace has been added to errors of the box.error module
2) Custom error type has been added. It's allows to create a new
error type in applications where the custom type is a subtype of error.

The next parts of the expose box.error task will include:
1) Transparent marshalling through net.box
2) Lua wrappers for the box.error interface
(it has to look like a https://github.com/tarantool/errors)
