Policy Engine - OPA for STYRA DAS Deployments

Issue

Policy Engine will return errors when using the OPA configuration using the following format for the OPA URL when also using Styra DAS (Declarative Authorization Service): .../v1/data For example, the following OPA URL: http://opa.tempcompany.com:8181/v1/data

Cause

Styra DAS deployments require changes to the OPA URL to read policies. Policy Engine expects that policies are in separate file/package namespaces for OPA to consume.  Styra DAS deployments place all policies in a single rules.rego package instead. The OPA URL needs to be adjusted as the policies will be in a different location for consumption.
