in daemon mode, don't stay in memory if there is no dynamic secrets
In case the template don't use dynamic secret, there is no need to stay in memory just. Before exiting, we must
- test that all template have been generated
- there is no dynamic secret fetched (renewable)
The secrets map need to map a secret path with a more elaborate structure (instead of a simple Option) containing a flag to know if the secret is renewable or not. When we fetch the secret we save the renewable flag inside the map.
