Explicitly specify ordered replication list for vshard storage

[R-omk]

Since the vsahrd storage call box.cfg and pass replication option, it can happen that the replication list is specified in a different order rather then if it do cartridge itself.

All this leads to that problem. tarantool/tarantool#7805

The place where we should explicitly pass the replication list:

cartridge/cartridge/roles/vshard-storage.lua

Lines 25 to 34 in 1aa826f

	local function apply_config(conf, _)
	checks('table', {is_master = 'boolean'})
	local my_replicaset = conf.topology.replicasets[vars.replicaset_uuid]
	local group_name = my_replicaset.vshard_group or 'default'
	local vshard_cfg = vshard_utils.get_vshard_config(group_name, conf)
	vshard_cfg.weights = nil
	vshard_cfg.zone = nil
	vshard_cfg.collect_lua_garbage = nil
	vshard_cfg.listen = box.cfg.listen

This way it can prevent the list from being populated randomly.
