DDL transaction abort unrelated transactions

[godzie44]

Bug description

Basically we observe that creating temporary space on replica forces <space_object>:format(<my new format>) to fail with transaction has been aborted by error. The reason of this error that one DDL transaction abort another DDL transaction without any reason (this is totaly independent transactions.

Steps to reproduce

Run two tarantool instances iteractively.

1. tarantool instanceA.lua
2. tarantool instanceB.lua

instanceA.lua:

local fiber = require('fiber')
local log = require('log')

box.cfg{
    listen = '0.0.0.0:3301',
    replication = { 'localhost:3301', 'localhost:3302' },
    log = 'instanceA.log'
}

box.once('grant guest', function() 
    box.schema.user.grant('guest', 'read,write,execute', 'universe')
end)

local format = {
    { name = 'field_1', type = 'unsigned' },
    { name = 'field_2',   type = 'string', is_nullable = true },
}    

local new_format = {
    { name = 'field_1', type = 'unsigned' },
    { name = 'field_2',   type = 'string', is_nullable = true },
    { name = 'field_3',   type = 'string', is_nullable = true },
}

local function alter_format()
    local space_a = box.space.A
    space_a:format(new_format)
    space_a:format(format)
end

local function create_space(space_name)
    local opts = {
        engine = 'memtx',
        format = format,
    }    

    local space = box.schema.space.create(space_name, opts)
    space:create_index(
        'primary',
        {
            unique = true,
            parts = {
                { field = 'field_1', type = 'unsigned' }
            }    
        }    
    )    
end    

local function fill_space(space_name)
    local iterations = 1000000
    local space = box.space[space_name]
    for i = 1, iterations, 1 do
        space:insert({ i, 'string' })
    end        
end    

create_space('A')
fill_space('A')

while true do
    local status, res = pcall(alter_format)
    if status ~= true then
        log.error('Error occured: '..res)
    end
end

instanceB.lua:

local fiber = require('fiber')
local log = require('log')
local uuid = require('uuid')

box.cfg{
    listen = '0.0.0.0:3302',
    replication = { 'localhost:3301', 'localhost:3302' },
    log = 'instanceB.log'
}

box.once('grant guest', function() 
    box.schema.user.grant('guest', 'read,write,execute', 'universe')
end)


local function create_space()
    local space_name = uuid:str()
    local space = box.schema.space.create(space_name..'_TMP', { type = 'temporary' })
    space:drop()
end

while true do
    local status, res = pcall(create_space)
    if status ~= true then
        log.error('Error occured: '..res)
    end

    fiber.sleep(0.1)
end

Actual behavior

2024-02-13 23:35:15.661 [50329] main/103/instanceB.lua memtx_tx.c:697 W> Transaction committing DDL (id=2001465) has aborted another TX (id=2001464)
2024-02-13 23:35:16.033 [50329] main/110/applier/localhost:3301 I> can't read row
2024-02-13 23:35:16.033 [50329] main/110/applier/localhost:3301 txn.h:566 E> ER_TRANSACTION_CONFLICT: Transaction has been aborted by conflict

Expected behavior

Cause space at instance B not depend on any space at instance A i'm expect that there is no conflicts here.
