Change parameters to extend ParameterGroupImpl

1. Changing all the forwarder parameter groups to extend the
ParameterGroupImpl instead of implementing the ParameterGroup interface.
2. Introducing lombok in distribution.
3. Fixing all the affected test cases.
4. Creating parameter group to hold parameters needed for forwarding
policies to the new lifecycle API's.

Issue-ID: POLICY-1890
Change-Id: I0c8b72f355a610fa5d46daaacc9ef7f06b7cec09
