Connect OCSP service to CertDB in order to send responses

I'm trying to use the `CA` and `OCSP` utilities from `CFSSL`, however I don't find any documentation related to setting a `OCSP` server to connect directly to a `certDB`.

What I did found was that the **`serve`** command offers the flags to initialize a _OCSP signer_, and from there _OCSP sign_ any issued certificates and then update the responses file required by the **`ocspserve`** command internally.

**Is there a better way to do this?** Since the method above requires to update the _OCSP service_ each time a new certificate is issued.
