Package certificates:

- rework package to allow convert config to model and retrive config from model
- add sub package to manage cipher, curves, auth client, tls version, certificates, root ca...
- add some small test (can be expande to having more coverage)
- optimize some code

Package httpcli:
- update code following change in certificates

Package httpserver:
- update code following change in certificates

Package Config/Components:
- update code following change in certificates

Package FTPClient:
- update code following change in certificates

Package Nats:
- update code following change in certificates
