Branch: https://github.com/tarantool/tarantool/tree/artemreyt/gh-5040-interactive-mode-bug
CI: https://github.com/tarantool/tarantool/runs/1929677579

Previous patch version: https://lists.tarantool.org/pipermail/tarantool-patches/2021-January/022144.html

Changes in v2:
  * core:
    - added `part of #5040` to the commit message;
    - rename `errinj_scan_env()` -> `errinj_set_with_environment_vars()`;
    - whitespaces refactored;
    - add test for setting error injections via environment variables;
  * lua:
    - little code refactoring after Sergey Bronnikov review (renames and move
    includes in the alphabetical order);
    - fixed bug, when test failed under high concurrency. There were about 20
    fails with 100 workers. Now, it's ok, tested with 300 workers om CentOS and
    macOS.
    (Bug resolved with removing temporary output_file after each testcase iteration);
    - moved ChangeLog to the last commit.
