[Feature flag] Enable Escalating manually created incidents
<!-- Title suggestion: [Feature flag] Enable description of feature -->
## Summary
This issue is to rollout [Escalating manually created incidents](https://gitlab.com/gitlab-org/gitlab/-/issues/330281) on production,
that is currently behind the `incident_escalations` feature flag.
<!-- Short description of what the feature is about and link to relevant other issues. -->
## Owners
- Team: Monitor ~"devops::monitor"
- Most appropriate slack channel to reach out to: `#s_monitor`
- Best individual to reach out to: @seanarnold / @crystalpoole
- PM: @abellucci
## Stakeholders
<!--
Are there any other stages or teams involved that need to be kept in the loop?
- Name of a PM
- The Support Team
- The Delivery Team
-->
## Expectations
### What are we expecting to happen?
Manually created incidents will escalate based on the Escalation Policy for the project.
<!-- Describe the expected outcome when rolling out this feature -->
### What might happen if this goes wrong?
<!-- Should the feature flag be turned off? Any MRs that need to be rolled back? Communication that needs to happen? What are some things you can think of that could go wrong - data loss or broken pages? -->
Escalations will not reach their intended recipients.
### What can we monitor to detect problems with this?
<!-- Which dashboards from https://dashboards.gitlab.net are most relevant? -->
## Rollout Steps
### Rollout on non-production environments
- Ensure that the feature MRs have been deployed to non-production environments.
- [x] Enable the feature globally on non-production environments.
- [x] `/chatops run feature set <feature-flag-name> true --dev`
- [x] `/chatops run feature set <feature-flag-name> true --staging`
- [x] Verify that the feature works as expected. Posting the QA result in this issue is preferable.
### Specific rollout on production
- Ensure that the feature MRs have been deployed to both production and canary.
- Enable for [project-actor](https://docs.gitlab.com/ee/development/feature_flags/#feature-actors):
- [x] `/chatops run feature set --project=gitlab-examples/ops/incident-setup/everyone/tanuki-inc incident_escalations true`
- [x] Verify that the feature works on the specific entries. Posting the QA result in this issue is preferable.
### Preparation before global rollout
- [x] Check if the feature flag change needs to be accompanied with a
[change management issue](https://about.gitlab.com/handbook/engineering/infrastructure/change-management/#feature-flags-and-the-change-management-process).
Cross link the issue here if it does. - N/A
- [x] Ensure that you or a representative in development can be available for at least 2 hours after feature flag updates in production.
If a different developer will be covering, or an exception is needed, please inform the oncall SRE by using the `@sre-oncall` Slack alias.
- [x] Ensure that documentation has been updated ([More info](https://docs.gitlab.com/ee/development/documentation/feature_flags.html#features-that-became-enabled-by-default)). - https://gitlab.com/gitlab-org/gitlab/-/merge_requests/80441
- [x] Announce on [the feature issue](https://gitlab.com/groups/gitlab-org/-/epics/5716) an estimated time this will be enabled on GitLab.com.
- [x] If the feature might impact the user experience, notify `#support_gitlab-com` and your team channel ([more guidance when this is necessary in the dev docs](https://docs.gitlab.com/ee/development/feature_flags/controls.html#communicate-the-change)). - N/A
### Global rollout on production
For visibility, all `/chatops` commands that target production should be:
- Executed in the `#production` slack channel.
- Cross-posted (with the command results) to the responsible team's slack channel (`#g_respond`).
- [x] [Incrementally roll out](https://docs.gitlab.com/ee/development/feature_flags/controls.html#process) the feature.
- If the feature flag in code has [an actor](https://docs.gitlab.com/ee/development/feature_flags/#feature-actors), perform **actor-based** rollout.
- [x] `/chatops run feature set incident_escalations 50 --actors`
- Enable the feature globally on production environment.
- [x] `/chatops run feature set incident_escalations true`
- [x] Announce on [the feature issue](https://gitlab.com/groups/gitlab-org/-/epics/5716) that the feature has been globally enabled.
- [x] Wait for [at least one day for the verification term](https://about.gitlab.com/handbook/product-development-flow/feature-flag-lifecycle/#including-a-feature-behind-feature-flag-in-the-final-release).
### Release the feature
After the feature has been [deemed stable](https://about.gitlab.com/handbook/product-development-flow/feature-flag-lifecycle/#including-a-feature-behind-feature-flag-in-the-final-release),
the [clean up](https://docs.gitlab.com/ee/development/feature_flags/controls.html#cleaning-up)
should be done as soon as possible to permanently enable the feature and reduce complexity in the
codebase.
<!-- The checklist here is to help stakeholders keep track of the feature flag status -->
- [x] Create a merge request to remove `incident_escalations` feature flag. Ask for review and merge it. - https://gitlab.com/gitlab-org/gitlab/-/merge_requests/80444
- [x] Remove all references to the feature flag from the codebase.
- [x] Remove the YAML definitions for the feature from the repository.
- [x] Create [a changelog entry](https://docs.gitlab.com/ee/development/feature_flags/#changelog).
- [x] Ensure that the cleanup MR has been deployed to both production and canary.
If the merge request was deployed before [the code cutoff](https://about.gitlab.com/handbook/engineering/releases/#self-managed-releases-1),
the feature can be officially announced in a release blog post.
- [x] Close [the feature issue](https://gitlab.com/groups/gitlab-org/-/epics/5716) to indicate the feature will be released in the current milestone.
- [x] Clean up the feature flag from all environments by running these chatops command in `#production` channel:
- [x] `/chatops run feature delete incident_escalations --dev`
- [x] `/chatops run feature delete incident_escalations --staging`
- [x] `/chatops run feature delete incident_escalations`
- [x] Close this rollout issue.
## Rollback Steps
- [ ] This feature can be disabled by running the following Chatops command:
```
/chatops run feature set incident_escalatations false
```
