Broken net_box compability between 2.11 and 2.10

[godzie44]

Originally this issue also reported a replication breakage, but this was moved to the separate issue #8757.

Bug description

After commit 13b0ce9 there is a broken messaging via net_box between tarantool 2.10 and 2.11.

Related versions:

• Tarantool 2.11.0-12-g807218ded (but you can use any version down to version 13b0ce9 inclusive)
• Tarantool 2.10.0-32-gd14267c64

Target: Linux-x86_64-RelWithDebInfo
Build options: cmake . -DCMAKE_INSTALL_PREFIX=/usr/local -DENABLE_BACKTRACE=TRUE
Compiler: GNU-11.3.0
C_FLAGS: -fexceptions -funwind-tables -fasynchronous-unwind-tables -fno-common -fopenmp -msse2 -Wformat -Wformat-security -Werror=format-security -fstack-protector-strong -fPIC -fmacro-prefix-map=/home/kostya/CLionProjects/tarantool-fork=. -std=c11 -Wall -Wextra -Wno-gnu-alignof-expression -fno-gnu89-inline -Wno-cast-function-type
CXX_FLAGS: -fexceptions -funwind-tables -fasynchronous-unwind-tables -fno-common -fopenmp -msse2 -Wformat -Wformat-security -Werror=format-security -fstack-protector-strong -fPIC -fmacro-prefix-map=/home/kostya/CLionProjects/tarantool-fork=. -std=c++11 -Wall -Wextra -Wno-invalid-offsetof -Wno-gnu-alignof-expression -Wno-cast-function-type

Steps to reproduce

1. run and configure tarantool 2.11 instance:

box.cfg{listen=3301}

2. run and configure tarantool 2.10 instance, then try to use net_box:

box.cfg{listen=3303}
conn = require('net.box').connect(3301)
conn:eval('print(1)')

This code return error:

- error: Invalid MsgPack - request body

Same behaviour with conn:call

There's a bug in Tarantool 2.10 because of which it fails to decode an IPROTO_ID packet from Tarantool 2.11. There's no workaround for it. We have to fix it in Tarantool 2.10 and make a new release.

The replication and net.box issues are unrelated. I filed the separate issue #8757 for the replication breakages and removed it from this ticket.
