oxisto: @immqu please have a look at the review comments
lebogg: @oxisto Dou you have any idea for solving the following GORM problem:
A certificate has a list of states. Both are migrated into GORM and accordingly associated. But we want that GORM to automatically fill the IDs of states (when Updating a certificate). If we let the id field empty, there will be one state only since it is overwritten every time. We also tried to exclude the id field hoping that GORM will solve it. But same problem.
There could be an option via gorm annotations of the state struct for default values. I didn't get it work but anyway, we cannot touch it since it is a generated file. There is a 3rd party package "protoc-gen-gorm" which I would like to avoid.

The only way that comes to my mind is, that we have to implement the lifecycle manager to always increment the state id if a new state for a certificate is created. It would be better though, if we just put the state w/o id and GORM does the rest.
