Describe your enhancement idea

Related to the changes from: #2813
We had an internal user point out that ProfileInfo.initSessCfg doesn't currently load hostKey from the profile and pass it into the session, so the caller has to explicitly pass that key in from the profile. Given that we automatically load other types of authentication/security related options here, I think it may make sense to update this list to include hostKey

Evaluate if other SSH properties like privateKey and keyPassphrase should also be added to the list.
