[Unexpected state] Delete connection

[benmoriceau]

Tell us about the problem you're trying to solve

Temporal can be in an unknown state because of a bug. This ticket is about addressing the scenario where no workflow exists and a delete connection is submitted.

This ticket is about implementing this diagram.

What is expected

When trying to submit a delete connection, if in the TemporalClient we detect that there is no existing temporal workflow, need to:

• Create a new workflow
• Submit a delete connection using a signal

No modification is expected in the ConnectionManagerWorkflow.
