With the change in the following PR, we don't need the `Deployment` finalizer anymore:
https://github.com/open-cluster-management-io/config-policy-controller/pull/100

This is because we need to account for uninstalls of the config-policy-controller when the entire namespace is deleted rather than just the `Deployment`.

Acceptance Criteria:

• Remove the finalizer on the config-policy-controller Deployment
• Increase the grace period to 120s seconds on the config-policy-controller pods so that when it is uninstalled, it has more time to clean up finalizers on the ConfigurationPolicy objects rather than the default 30 seconds.
