Container Scanning Continuous Vulnerability Scans, also known as
Continuous Container Scanning, allow for GitLab instances to scan known
software components for newly released advisories. This feature is now
enabled by default, but can be disabled if needed by disabling the
`:container_scanning_continuous_vulnerability_scans` feature flag.

If code_suggestions_claude21 flag is enabled, we set explicitly
model_name=claude-2.1. If the flag is not set, we use AI gateway's
default model (currently claude-2.0).

When the flag is enabled, then user-level code_suggestion check is
skipped, and also this setting is not exposed to user.

Adds whole file content (if it's small enough) to prompts used by slash
commands. This additional content may be useful in some use-cases - e.g.
refactoring the code, or explaining it.

This change implements fair queueing for the loose foreign keys feature.
If the child records of a deleted record batch cannot be cleaned up in
3 consequitive executions then the deleted record batch will be
re-scheduled 5 minutes later.

This fixes usage of `after_commit` - a set of operations
that are executed after the object is committed. Before that
change the operations would be treated as being executed
in context of a transaction, even though the transaction
was already finished.

This introduces trace record object that receives callback
once the after commit/rollback hooks are to be executed.

This adds a Rack middleware and Sidekiq middleware for detecting
"Cross-database modification" violations. These occur when you query 2
different databases in the context of a single transaction. Previously
we only wrapped our RSpec code with this detection logic but we found
that it was often causing lots of false positives in RSpec (in test-only
code) which made it hard to sort through the real issues. In addition we
want extra validation by running this in production and therefore
detecting code that our specs may be missing.

The middlewares use a feature flag `detect_cross_database_modification`
which we intend to enable for a small percentage of time.

The middlewares can also be disabled by setting the env var
`DISABLE_CROSS_DATABASE_MODIFICATION_DETECTION=true` and restarting the
application. This environment variable is an extra safety net if the
middlewares are causing problems.

This introduces a `GITLAB_USE_MODEL_LOAD_BALANCING`
and `use_model_load_balancing` to enable percentage rollout
of used connection when accessing data.

The usage pattern is to redirect 1% of new connections using CI DB
to use a Load Balancer replicas (and presumbly later primary connection).

This is achieved by injecting a FF evaluation logic as part of LB setup
to re-define how connection is fetched.

This change adds worker and services for cleaning up orphaned
associations.

  - GitLab Group Migration now includes empty projects
    migrated from source instance of GitLab if
    bulk_import_projects feature flag is enabled

Github Labels, Releases and Milestones uses a different approach to be
imported. These objects were not being counted, or logged, in the same
way of the rest of Github objects.

Related to: https://gitlab.com/gitlab-org/gitlab/-/issues/335199
MR: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/65773

This iterates all YAMLs, and fetches milestone
associated with the MR or Issue.

This also organises items of all YAMLs in a consistent
order.

- In order to add Group Import V2 using API first step
  is to add an ability for user to provide auth credentials
  for GitLab to use in order to authenticate with source GitLab
  later on

Updated for test setup, restructured startup setup

Restructured to have a feature flag in place
for startup_css

Created the security_on_demand_scans_site_profiles_feature_flag feature
flag for using exisint DAST site profiles when running On-demand Scans.
