add support for pld linux via apply script provided by recipe

add support for pld linux via apply script provided by recipe

the difference with default.rb is what is actually notified:

    notifies :start, "bash[apply-sysctl]", :immediately

vs 

     notifies :start, "service[procps]", :immediately

so imho the cookbook would require first some cleanup to add support for different "apply" modes and have subrecipe ased on that.

i liked how it was done in [timezone-ii](https://github.com/L2G/timezone-ii/blob/master/recipes/default.rb) cookbook:

    case node.platform_family
    when 'debian', 'fedora'
      include_recipe "timezone-ii::#{node.platform_family}"
    else
