[APM] Cannot create transaction duration rule outside of context of APM app

[dgieselaar]

When the user wants to create a transaction duration rule outside of the context of the APM app, the trigger component never renders, as serviceName is missing. The consequence is that the user cannot create these rules outside of the APM app.

To solve this, we could implement a free-form text field to allow the user to set serviceName themselves. This would also open the possibility of using this for environment and transactionType, and allowing the user to create this rule anywhere in the APM app, rather than just in the context of a specific service.

Might be related to it, currently when I try to create an alert having transaction type: All an error happens fixed in #107942:

[dgieselaar]

We could make it clear to users that they cannot create alerts from here:

  );
  
  if(!metadata?.serviceName) {
  	return <EuiCallout>Creating alerts from here is not supported. Please go to the [APM app](link))</EuiCallout>
  }

Is this a duplicate of #106786?

Sort of. #106786 refers to editing existing APM alerts, while this issue is about creating new APM alerts from Stack Management. I think the solution is the same (free form text fields), and they could probably be grouped as a single ticket "Ability to add and edit alerts outside of APM UI"

Unless there's any objections I'll close this one.
