Subject: [PATCH 03/24] Fix fedora shadow permissions

Fedora belongs in our tests to the RH family,
lets make it explicitely here, as ohai detects platform_family on fedora
as 'fedora' and not 'rhel'.

See https://github.com/dev-sec/linux-baseline/pull/82 for reference

+### Controlling the included components
+
+`default.rb` includes other components based on the ohai autodetection attributes of your system. E.g. do not execute selinux on non-RHEL systems. You can override this behavior and force components to be executed or not via setting attributes in `node['os-hardening']['components']` on the override level. Example
+
+```ruby
+# some attribute file
+# do not include sysctl and auditd
+override['os-hardening']['components']['sysctl'] = false
+override['os-hardening']['components']['auditd'] = false
+
+# force selinux to be included
+override['os-hardening']['components']['selinux'] = true
+```

+In the current implementation different components are located in the different recipes. See the available recipes or `default.rb` for possible component names.

Subject: [PATCH 20/24] use sysctl 1.0 (#210)

* use sysctl cookbook 1.0

most of the code was already written by symondsandson
https://github.com/symondsandson/chef-os-hardening.git

remove the sysctl attributes file - values are now set in the recipe
remove the lazy evaluation from symondsandson
adapt test cases to test usage of sysctl_param resource

* use again node attributes for sysctl param values

This should be done to ensure downward compatibility and keep flexibility. See discussion on:
https://github.com/dev-sec/chef-os-hardening/pull/210
