Set sync setting in config automatically

[yiraeChristineKim]

Description: The gatekeeper operator exposes a setting in the CRD under audit named auditFromCache. By default this cache is Disabled. If you set it to Enabled, you break your constraints because the cache requires additional settings in the CRD configs.config.gatekeeper.sh for the sync details.

The problem (my opinion here) is that if we expose the ability to enable the cache in the operator we must also expose the ability to configure the cache with the sync details.

Wow! This is quite the PR, @yiraeChristineKim! I need to look at the E2E test and look through the Gatekeeper docs to figure out the pieces here and the details on what it's doing, but it'll be a powerful addition to the operator!

I have some comments/questions that I thought I'd leave in the meantime.
