Use new RestClientParameters class in distribution

Replaced LifecycleApiForwarderParameters with RestClientParameters.
Also modified the code to get the HttpClient objects once.

This requires changes to property files in CSITs and OOM:
- rename "hostName" to "hostname"
- rename "isHttps" to "useHttps" and move it inside the api & pap
  structures

Issue-ID: POLICY-3456

Change-Id: I654c32c9b6628263a68d821e11c5a316e8b6e2cc
