Nit: It is over 72 symbols. See

Nit: Such metainfo usually placed under '---' marks to match `git am`
patch format: text under '---' is not part of a commit message.

A commit message should contain 'Part of #4801' or so.

ERRINJ_AUTO_UPGRADE is false by default, so the default behaviour
becomes "don't upgrade". I think you meant:

 |     if not box.cfg.read_only and not box.cfg.replication and
 |        not box.error.injection.get('ERRINJ_AUTO_UPGRADE') then
 |         box.schema.upgrade{auto = true}
 |     end


Nit: Over 80 symbols.

ERRINJ_AUTO_UPGRADE is not different from other injections, let it be in
`ekeys`. Just update the result file.
