- Refactors the existing cert generation code into controllers
which read and write a Secret containing the certs
- Does not add any new functionality yet, e.g. no new handling
for cert expiration, and no leader election to allow for
multiple servers running simultaneously
- This commit also doesn't add new tests for the cert generation
code, but it should be more unit testable now as controllers
- Not strictly necessary at the moment because both our build layer
and our run layer are based on alpine, but static linking our binary
will help us later when we want to base our run image on something
closer to scratch
