See merge request gitlab-org/gitlab-ce!29903

This is a small change to move AfterCommitQueue.inside_transaction?

by different changes which may not arrive in sequence, it's easier
to extract this change out on it's own.

Fix reports jobs timing out because of cache

Closes gitlab-ee#12021, #60879, and gitlab-ee#11303

See merge request gitlab-org/gitlab-ce!29780

Note: This commit relies on
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/26801
which brings support to multiple extends.

While `cache: {}` can disable a cache being set globally, it doesn't
work with extends, which will perform a reverse deep merge based on the
keys.

The cache defined in the base `.default-cache` job
won't be disabled in the report jobs.

As a side effect, the `code_quality`, `sast`, and `dependency_scanning`
jobs are running on a larger code base than expected, leading to
timeouts.
