[Tarantool-patches] [PATCH v2] Add new error injection constant ERRINJ_AUTO_UPGRADE

[sergeyb@tarantool.org]

From: Sergey Bronnikov <sergeyb@tarantool.org>

In upgrade testing we need an ability to control running of upgrade.lua
script execution. When constant ERRINJ_AUTO_UPGRADE is set to true
tarantool will skip upgrade.lua script execution.

Part of: #4801
