unique names for ohia resource

[coreyappleby]

Chef 13 doesn't allow resource cloning, so the ohai "reload" resource needs unique names for client and server.

Previous ohai[reload]: /tmp/kitchen/cache/cookbooks/ssh-hardening/recipes/server.rb:43:in from_file'
Current ohai[reload]: /tmp/kitchen/cache/cookbooks/ssh-hardening/recipes/client.rb:23:in from_file' (CHEF-3694)/tmp/kitchen/cache/cookbooks/poise/files/halite_gem/poise/helpers/resource_cloning.rb:58:in emit_cloned_resource_warning'.
Please see https://docs.chef.io/deprecations_resource_cloning.html for further details and information on how to correct this problem. at /opt/chef/embedded/lib/ruby/gems/2.3.0/gems/chef-12.22.5/lib/chef/formatters/doc.rb:419:in deprecation'
