Add ability to modify HTTP CONNECT proxy initialization

This patch adds HTTPTrafficFilter and integrates it into HTTPConnectProxiedConnection. This allows the HTTP CONNECT proxy initialization process to be customized. Test-Information: Added a unit test that verifies the new functionality. Change-Id: I0b93c319fb205487b8be65717276cd0dd38851a3
