Notebook(Alerts): Zenoss Alert export generates flux script that cannot be compiled

_Note_ - for this test we are temporarily using a simple HTTP echo server in EC2 before creating and testing against an actual Zenoss account.

## About the bug

**Steps to reproduce:**
List the minimal actions needed to reproduce the behavior.

1. Setup a listener to receive Zenoss messages.
2. Go to Influxdbv2 UI (note that during this test the feature flag 'notebooksNewEndpoints' was set)
3. Add test data to a bucket
4. Create an Alert Notebook
5. Use the test data to define the query
6. In the alert section choose Zenoss
7. Add the username, password, severity, action, method and change the URL to point to the listener, if not testing against the actual Zenoss service.
8. Click "Export Alert Task"
9. Open the generated task in the tasks view
10. Click "Run Task". This schedules a run
11. After a moment open the Task List.

**Expected behavior:**

Expected the task to be run and a message to appear at the listener

**Actual behavior:**

The Last Run status is Error.
Open the Task Editor. The generated flux script cannot be compiled.

**Visual Proof:**
