Current it is not possible to create box.error() (struct error) objects without throwing them. Let's bind box_error_new() C API to Lua.

Title: box.error.new() - create an error object with no throw
box.error.new(error_code, args) - the way to create an error object and do not throw it, but just return as the simple object. It is useful when an error object must be saved to be got later, for example.

tarantool> e = box.error.new(box.error.CREATE_SPACE, "space", "error")
tarantool> e
---
- 'Failed to create space ''space'': error'
...
tarantool> e:unpack()
---
- type: ClientError
  code: 9
  message: 'Failed to create space ''space'': error'
  trace:
  - file: '[string "e = box.error.new(box.error.CREATE_SPACE, "sp..."]'
    line: 1
...

It is needed to return error via 'nil, error_object' notation,
and to store an error object to return it later.
