Will SSL Termination details be passed through HTTP headers? If so, what will be the http header names?
Also "ssl_policy.pass_info" is a string, how does it work?
Do you see a strong use case? Otherwise this can be skipped for phase-1.

"Trusted Certificate" seems fine.
"ssl_trusted_key (new)" datamodel and its properties are still not changed. You might want to rename ssl_trusted_key* => ssl_trusted_certificate*
ssl_trusted_key_id also can be renamed

There are still keys used in place of certificate
public_key : PEM-formatted string
