Now that we support total counts with 7d and 28d time frames, we can
stop using a distinct counter to implement the
redis_hll_counters.code_review.i_code_review_create_mr_*
metrics and instead count the number of i_code_review_user_create_mr
events triggered.

Changelog: changed

- Adds event model_registry_ml_model_created
- Adds event model_registry_ml_model_version_created
- Adds metrics for both events on 7d and 28d

Changelog: added

The same metric was defined in these two files
20211126090835_p_analytics_ci_cd_deployment_frequency_monthly.yml
20211126090002_p_analytics_ci_cd_deployment_frequency.yml

The root property `events` is used by metrics with the `data_source: internal_events`.
Sometimes we forget to update the `data_source` when we migrate a metric from RedisHLL to InternalEvents.

This change makes sure the spec will fail if we add a `events` root property and keep the `redis_hll` `data_source`.

Adds the counts.service_desk_custom_email_enabled
metric to Service Ping. Provides the number of projects
that have Service Desk custom email enabled.

This is to prevent GitlabSettings::MissingSetting, as you apparently
can't stub a non-existing example setting with `stub_config`.

Stricter validation of Aggregated & Total metrics

Add stricter metrics validation

Migrated ci_templates_unique Snowplow event to
internal event named ci_template_included.

This adds instrumentation classes for issue_imports.jira and
issue_imports.csv metrics and removes them from Gitlab::UsageData, which
is a legacy way of including them in a Service Ping payload.

This quick action adds a work item as a child to the current work
