[DISCUSS] KIP-828: Add the corresponding validator to the configuration where the validator is missing

[Riven Sun]

Hi devs,  I've created a KIP that aims to add the corresponding validator
to the config where the validator is missing.
In order for the program to detect these incorrect configurations during
initialization:

Please take a look and let me know if you have any feedback. Thanks. Riven
