Make CreatePipelineService to use a dry_run mode

See merge request gitlab-org/gitlab!37134

This allows a pipeline creation to fully run while skipping
the persistence steps. In the end it returns a non-persisted
pipeline with all its errors and warnings.

This feature is useful to allow CI Lint to use the actual
pipeline creation and display all errors rather than using
only YamlProcessor.

Load project list only during loading the Security Dashboard

See merge request gitlab-org/gitlab!39263

At the moment, users have no way to clean up orphaned LFS objects in
their repositories. Ideally, this would happen automatically, but in
the meantime, making it part of project housekeeping - which can be
manually triggered, and is also used during project cleanup, which is
often used as part of the "remove LFS from this repository" flow -
solves a pressing need.
