Make org.forgerock.openam.agents.config.policy.evaluation.* optional

As of OpenAM 12.0.x, users no longer need to have referral policies under default realm . This is because OpenAM 12.0.0 now enables you to specify the realm and application in the policy agent profile. When PA is configured with specific realm and application type, OpenAM directs requests from the policy agent to the specified realm and application.

However, this feature is slowing down the speed to get PolicyEvaluator within PolicyRequestHandler. OpenAM 12 takes 37 ms till it printed out "Policy Manager constructed with..." message where as OpenAM 9.5.5 takes ~10 ms:

Policy Manager constructed with SSO token  for organization: dc=jpl,dc=nasa,dc=gov

This is because PolicyRequestHandler is retrieving PA's profile (this involves checkPermission etc), then tries to get all related application types PA admin can evaluate.

One option is to turn off this feature if "Activate Referrals:" is on or introduce a new flag.
