[doakalexi]

Towards: #169867

This PR onboards the Transaction Error Rate rule type with FAAD.

To verify

1. Run the following script to generate APM data:

node scripts/synthtrace many_errors.ts --local --live

2. Create a transaction error rate rule.
   Example:

POST kbn:/api/alerting/rule
{
  "params": {
    "threshold": 0,
    "windowSize": 5,
    "windowUnit": "m",
    "environment": "ENVIRONMENT_ALL"
  },
  "consumer": "alerts",
  "schedule": {
    "interval": "1m"
  },
  "tags": [],
  "name": "test",
  "rule_type_id": "apm.transaction_error_rate",
  "notify_when": "onActionGroupChange",
  "actions": []
}

3. Your rule should create an alert and should saved it in .internal.alerts-observability.apm.alerts-default-000001
   Example:

GET .internal.alerts-*/_search

4. Recover the alert by setting threshold: 200

5. The alert should be recovered and the AAD in the above index should be updated kibana.alert.status: recovered.
