Request: Validate Schema / Reject unknown keys

[edude03]

Problem
Spent two days trying to figure out why TLS didn't work, turns out it's tls.enable not tls.enabled.

It should error when an incorrect key is set.
Persona:
Which persona is this feature for?
System Operator / Contributor?

Exit Criteria
A measurable (binary) test that would indicate that the problem has been resolved.

Passing tls.enabled should prevent the CRD from being saved.

Time Estimate (optional):
How many developer-days do you think this may take to resolve?

Additional context (optional)
