Support loggingConfig for GKE clusters

[hsharrison]

What problem are you facing?

I've configured a custom fluent-bit deployment in a crossplane-managed Cluster in GKE. I'm getting duplicated logs because the GKE fluentbit and the custom fluentbit are both parsing the stdout/stderr of the containers in the cluster.

The typical recommendation in this case, as far as I understand, is to configure the cluster to only collect system logs, exposed in the REST API as loggingConfig.

How could Crossplane help solve your problem?

Support passing loggingConfig in spec.forProvider of `Cluster.
