/dlp/rest/v1/policy-levels/<data_ type>
The GET method of the policy level API retrieves all policy levels that are available for user in the Manage Policy section of DLP Policies and Discovery Policies screen. The data_type should be either NETWORKING or DISCOVERY.
Note: Policy levels must have unique names within the same datatype (NETWORKING, DISCOVERY), but the same name can be used in both types.
