Deprecate strict_policy_enforce configuration option

The configuration option ``[patrole] strict_policy_check``
is deprecated and will be removed in the Rocky release cycle.

The default value for ``[patrole] strict_policy_check`` has
been changed to ``True`` because a Patrole test should always
fail if the policy action is invalid, to avoid false positives.
