[APM] Documentation updates (#160568)
### Summary

This PR makes a handful of updates to the APM app documentation:

- [x] **Alerts tab, workflow, and grouping**
- Rewrote most of our [alerting
documentation](https://kibana_160568.docs-preview.app.elstc.co/guide/en/kibana/master/apm-alerts.html#apm-alert-view-active)
to explain the new granularity level of alerts, address new alert names,
and explain the different ways to view active alerts.
- Updated the
[Services](https://kibana_160568.docs-preview.app.elstc.co/guide/en/kibana/master/services.html)
documentation to describe the alert badge and link to alerting docs.

- [x] **Infrastructure tab**

=== Infrastructure
The *Infrastructure* tab provides information about the containers, pods, and hosts,
that the selected service is linked to.

IT ops and software reliability engineers (SREs) can use this tab
to quickly find a service's underlying infrastructure resources when debugging a problem.
Knowing what infrastructure is related to a service allows you to remediate issues by restarting, killing hanging instances, changing configuration, rolling back deployments, scaling up, scaling out, etc.
