cmd/k8s-operator: remove configuration knob for Connector (#10791)

The configuration knob (that defaulted to Connector being disabled)
was added largely because the Connector CRD had to be installed in a separate step.
Now when the CRD has been added to both chart and static manifest, we can have it on by default.
