Build PIP Server

[wunder957]

Policy Information Point (PIP): Serves as the retrieval source of attributes, or the data required for policy evaluation to provide the information needed by the PDP to make the decisions. NIST SP 800-162.

In version 0.1.0 we will provide the base PIP service, which should not be limited to the existing tracer and collector implementations, and I think we should introduce an indirection layer to isolate the PIP service from the existing trace/collection mechanisms. And maybe this indirection layer is what's called an analyzer.
