[APM] Anomaly detection: Display Anomaly detection option in the APM header

[formgeist]

Summary

Related to elastic/apm#280 and #69479

We want to display an option in our general APM header that will allow the user to go and setup Anomaly detection easily from anywhere in the UI. We will additionally increase visibility for users who have the available capabilities in their license to enable the integration immediately and get the value expected from it e.g. on the Service maps view.

Solution

Show an Anomaly detection option in the general APM header.

Anomaly detection has yet to be enabled

We will make the option especially visible when the Anomaly detection feature is yet to be enabled by two criteria;

1. No anomaly detection jobs have been found for any environment in the data
2. No job available for the selected environment e.g. user selected staging we'll display a highlighted icon next to the button to draw attention to it.

Additionally, we would like to show a tooltip on hover to explain the highlighted icon. The text will be dynamic to display either an all or specific environment message.

Anomaly detection is already enabled for environment(s) or license privileges are insufficient.

If there are jobs enabled for....

• the currently selected environment
• or any of the environments when All is selected

we will display the default button icon state.

The default state will also be shown when the license privileges do not allow for the integration to be enabled unless they start a trial. The start trial message will appear in the Settings view as described in [add a link to the issue – @formgeist ]
