Create SSL Certificates using Forge

[fboucquez]

Atm, node SSL certificates are being created via docker images. Ideally, we should migrate them to a native forge implementation:

1. Faster
2. Remove docker dependency for the config command. Users just using the tool for config won't need docker, like Raspberry Pi users.

Something like this may do the trick. The certificate should use ed25519 algorithm.

This task will modify the CertificateService

Security update: if we remove the docker requirement, Bootstrap will one step closer to full offline config
