[Tarantool-patches] [PATCH] box: check schema version after tarantool update

From: Sergey Voinov <sergeiv at tarantool.org>
Check schema version (stored in box.space._schema) on start and
print a warning if it doesn't match last avaliable schema version.
It is needed bcause some users forget to call box.schema.upgrade()
after Tarantool update and get stuck with an old schema version
until they encounter some hard to debug problems.
Closes #4574
---
@ChangeLog: Print log warning if schema version is older than last available schema version (gh-4574).
Branch: https://github.com/tarantool/tarantool/tree/servoin/gh-4574-schema-version
