For authentication, add both an audit event and authentication
event for the short term. Eventually we will diverge and only
store authentication events when an authentication occours.
At that time, authentication events will be a subclass of audit
events. For now we store both and use authentication events for
usage ping exclusively.

AuthenticationEvent will track sign-ins via providers such as LDAP,
SAML, and other OmniAuth/OAuth providers. The end goal is to report
usage of each authentication method via Usage Ping. In the future
this will be an extension of AuditEvents specific to authentication.

Fail pipeline early when there is rspec failure related to MR changes

See merge request gitlab-org/gitlab!41081

Add rspec fail-fast job
- This job runs rspec on test files detected by
  the job `detect-tests`.

Add fail-pipeline-early job
- This job cancels the current pipeline in order
  to provide fast feedback upon test failure.
  This happens when the `rspec fail-fast` jobs has failed.

Add toggle to enable `rspec fail-fast`
- The rspec-fail-fast and fail-pipeline-early jobs
  will only be created if the RSPEC_FAIL_FAST_ENABLED variable
  is "true".
- Using this flag, we can experiment with this pipeline
  change with more control.

Add option to skip rspec fail-fast
- Using MR title SKIP RSPEC FAIL-FAST
- Using dont-interrupt-me job

Add Enum support for `deprecated` argument

See merge request gitlab-org/gitlab!41630

`ruby-graphql` supports

https://gitlab.com/gitlab-org/gitlab/-/merge_requests/27464 added support
for a custom `deprecated` keyword for `field` to allow us to specify the
milestone that a field was deprecated in a structured way.

Enum values are also able to be deprecated. This change adds support for
enum values.

GraphQL - Expose group memberships under group

- Use GroupMembersFinder

Previously, we've created and applied the "incident" label
only when calling the `IncidentManagment::Incidents::CreateService`
explicitly. After we've added the issue type "incident" incidents
can be created/updated using the `Issues::Create/UpdateService`.
Those services did not apply this label.

This commit moves the code which applies the label close to the
`Issue` services to make sure we are labeling all incidents with
the "incident" label correctly.

Reduce the total amount of factories from 260 to 43 cutting
the total amount of events in half.

Exclude tmp dirs from backups

See merge request gitlab-org/gitlab!41706

Add '--exclude' for tmp directories in located in paths included in
backups.  Currently a backup job may fail due to a file or directory
within a tmp dir being removed during the backup.

This change adds a new 'exclude' optional parameter to Backup::Files
to indicate directories that should not be included in backups. This
should prevent changes in temporary files from breaking backups and
also stop unneeded files from being included in the backup archive.
