Instead of modifying the runner, use config hooks to skip quarantined
tests, and to allow only quarantined tests to be run, if desired.

This way quarantined tests are skipped, not excluded completely, so
they are still included in test results.

This reverts commit 8ef418d57c5a9511b862bf0711aadbb977086c91.

Exclude quarantined tests by default.

Import issues from CSV

Closes #49231

See merge request gitlab-org/gitlab-ce!23532

In the previous code, we locked the project during the migration
scheduling step, which works fine for small setups, but can be
problematic in really big installations.

We now moved the logic to inside the worker, so we minimize the time a
project will be read-only. We also make sure we only do that if
reference counter is `0` (no current operation is in progress).
