After CFE-81 we understand the k8s schema better, so we can detect and obfuscate things like ssh keys in machine configs:

AC:
- both line based and schematic obfuscation should support a new type "ssh key" that will detect and obfuscate ssh keys
- it should be enough to omit the base64 hash in the static obfuscation, alternatively the consistent replacement can give that key a name with increasing id.
