Hi, Igor!
Thanks for the patch!
LGTM, except for a few nits regarding the commit message:
 
Понедельник, 27 февраля 2023, 12:10 +03:00 от Igor Munkin <imun@tarantool.org>:
 
Sometimes one need to skip the remaining tests in the script. There is
no special stub in TAP13 protocol for this, but this could be done via
Typo: s/TAP 13/the TAP 13/
skipping all the remaining planned tests.

Within this commit <test:skiprest> helper is introduced that calls
<test:skip> (planned - total) times and exits the test script. As for
the previous commit it's worth to mention, that skiprest helper is
Typo: s/worth to mention/worth mentioning/
implemented only for root (i.e. test with no parent) tests and subtests
are not supported at the moment. The corresponding assertion with FIXME
reason can be found in <finalize> routine.
