Ability to sign a CSR using api.

[devatnull]

Is your feature request related to existing pfSense functionality that is missing from the API? Please describe. Can not sign a CSR using the api.

Is your feature request related to a problem? Please describe. No.

Describe the solution you'd like I would like to sign a CSR.

Describe alternatives you've considered Implementing methods to createcert function would be fine i believe.(user must know the CA refid first.)
