Import issues from CSV

Closes #49231

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

References with namespace are inserted because this is at group scope
and iids are not unique

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).

Skip parsing of container scanning report if feature flag is disabled.
