Description of problem:

The template sync controller reconciles every time a policy template is updated. The config-policy-controller updates the `lastEvaluated` status on the ConfigurationPolicy, which by default is every 10 seconds. This can get noisy if you have a lot of policy templates and can cause important logs to be lost when debugging an issue since the logs rollover at a certain point.

Logs such as this are not useful and instead, we should only log when something changes or is unexpected:
