Single view in app function for rule actions variables and UI page (#…

…148671)

Resolves: #145132.

In this PR, I'm adding a new function to the server-side rule type
definition called `viewInAppRelativeUrl`. This function returns a
relative path to view the rule in the proper application that will
provide more context. This relative path is used to build the `rule.url`
mustache variable for the actions (overriding the rule details page link
when defined) as well as a fallback for the UI's `View in App` button if
no navigation is registered on the front-end.

Follow up issues:
- #149608
- #151355

## ML to verify

1.  Create an anomaly detection rule from the ML application
2. Go to stack management rule details page
3. Click "View in App"
4. Ensure it brings you to the ML app properly.
5. Repeat step 1 to 4 in a space that isn't the default

Note: ML won't take advantage of the new functionality yet, but we plan
to help in a follow up #149608
so that ML anomaly detection rules can provide a view in app URL within
the rule action messages.

## ResponseOps to verify

1. Set `server.publicBaseUrl` to the proper value in your kibana.yml
6. Modify the [index threshold rule
type](https://github.com/elastic/kibana/blob/main/x-pack/plugins/stack_alerts/server/rule_types/index_threshold/rule_type.ts#L108-L136)
to have a `getViewInAppRelativeUrl` function returning
`/app/management/insightsAndAlerting/triggersActionsConnectors/connectors`.
7. Create an index threshold rule that always fires. Make sure to add a
a server log action that contains the `{{rule.url}}` variable.
8. Pull the printed URL from the server logs and make sure it works and
brings you to the connectors page.
9. Navigate to the rule details page, click the "View in App" button and
ensure it also brings you to the connectors page.
10. Create a Kibana space.
11. Go into that created space and repeat step 3 to 5. Ensure the URL
and View in App keep you in the same space.

 This tells the Alerting Framework that, given a rule of the RuleType whose ID is `my-application-id.my-unique-rule-type`, if that rule's `consumer` value (which is set when the rule is created by your plugin) is your application (whose id is `my-application-id`), then it will navigate to your application using the path `/my-unique-rule/${the id of the rule}`.
 
-The navigation is handled using the `navigateToApp` API, meaning that the path will be automatically picked up by your `react-router-dom` **Route** component, so all you have top do is configure a Route that handles the path `/my-unique-rule/:id`.

 You can look at the `alerting-example` plugin to see an example of using this API, which is enabled using the `--run-examples` flag when you run `yarn start`.
