Previously the nullification wasn't done, as the only caller would later
destroy the model all together. In
https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/9070 this change
was made. This commit is basically a backport before that MR is merged.

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).

In the administration page for web terminals add a new `Security`
section explaining how the interactive web terminals are secured between
GitLab and gitlab-runner.

This section is under administration instead of
`doc/ci/interactive_web_terminal` because the administrators of the
GitLab instance would be mostly interested in this, whilst
`doc/ci/interactive_web_terminal` are interested in how the feature
works.
