Policy support to modify query parameters in request/response path

[BLasan]

Problem

A separate policy support is needed to modify request/response query parameters. This is specifically needed for WebSub APIs as the WebSubHub understands the tasks by query parameter

Ex: hub.mode query parameter is needed when publishing data to the topic. WebSubHub validates whether hub.mode=publish before publishing it to the topic.

Proposed Solution

Policy engine should support a policy setQueryParameter and removeQueryParameter (To remove and add query parameters in request/response paths)
