feat(authsign): store additional metadata/fields in certdb (#1126)
This is a major change in that the included DB migrations *must* be run before the new version of `cfssl` is deployed. This allows for clients (i.e. https://github.com/cloudflare/certmgr) to send some additional optional fields to `/api/v1/cfssl/authsign` to be stored in `certdb`. It also starts saving SANs, common name, and NotBefore from the issued certificates so that they can be queried without having to parse the PEM.
