Implement policy provider functions

Includes:
a) Implement policy provider functions
b) Implement policy type provider functions
c) Implement legacy guard policy provider functions
d) Implement legacy operational policy provider functions
e) Modify API endpoints to align with provider functions
f) Hook up API statistics counter

Junit tests for providers and new endpoints will be in next patch/review.
