Summary
Add support for configuration of HostCertificate files in the sshd service. This allows the use of pre-signed SSH host keys to be deployed to VyOS hosts.
Use case
This allows users to skip the "trust-on-first-use" by having pre-signed and validated SSH host keys.
No more prompts like this:
The authenticity of host 'vyos.example.com (2001:db8::1)' can't be established. ED25519 key fingerprint is SHA256:zJ+clLpAPHB+KLlj0A3mAvNQkaoUyu8qOTx6tc+k1McEI. This key is not known by any other names. Are you sure you want to continue connecting (yes/no/[fingerprint])?
