Fail redis and mongo tests if incorrect URI provided + some storages tests refactoring (#1510)

* Smaller timeout for MongoStorage connection

By default serverSelectionTimeoutMS=30000. This is too much

* Correct ConnectionError for RedisStorage in tests

* Remove unused import in conftest.py

* Refactor skipping redis and mongo tests

* Fail redis and mongo tests if incorrect URI

If incorrect URIs provided to "--redis" and/or "--mongo" options
tests should fail with ERRORs instead of skipping.
Otherwise the next scenario is possible:
  1) developer breaks RedisStorage and/or MongoStorage code
  2) tests are run with incorrect redis and/or mongo URIs
     provided by "--redis" and "--mongo" options.
     For example, wrong port specified.
  3) tests pass because skipping doesn't fail tests run
  4) developer or reviewer doesn't notice
     that redis and/or mongo tests were skipped
  5) broken code gets in codebase

* Remove unused fixtures passing in storages tests

* Define create_storage_key fixture in conftest.py

* Linters formatting

* Changes description

* Revert "Smaller timeout for MongoStorage connection"

This reverts commit d88b7ec612.

* Smaller timeout for MongoStorage connection in tests

The default 30s timeout is too long

* Add test for MongoStorage for 100% coverage

* Linters formatting

* Move skipping redis/mongo tests in earlier fixtures

* Replace vars with constants in conftest.py

* Linters formatting
