feature/box: first box and box.info implementation

[KaymeKaydex]

I implemented the box interface for tarantool with a small number of fields, which in the future can be supplemented

I didn't forget about (remove if it is not applicable):

• Tests (see documentation for a testing package)
• Changelog (see documentation for changelog format)
• Documentation (see documentation for documentation style guide)

The problem with this approach is that it cannot be extended. As example:

1. How to use a context with the method? How to cancel the request?
2. How to make an async request?

It's better to implement a custom request type, as it is already done in the crud and the arrow subpackages. It is possible to implement a custom response type for a request too:

go-tarantool/example_test.go

Line 577 in 8cf8673

exResp, ok := resp.(*tarantool.ExecuteResponse)

In the Tarantool 3 the field has name replicaset.
