fixes #4155 - enable host/CR (dis)association via api
Fixes #6528 - Silence seeds.rb when in test env

fixes #6441 - allows filtering of parameters per controller

There is an issue where certain parameters for particular
controllers are causing the log to fill up. This allows the ability
to filter parameters by controller.

This allows each controller to add additional parameters to filter.
In a controller, to filter parameters name and description, you can add
the following:

include Foreman::Controller::FilterParameters
filter_parameters :name, :description
