Drop EoL cisco support

[bastelfreak]

Puppet doesnt support cisco anymore since some time.

In spec/beaker/dsl/test_tagging_spec.rb I still see some cisco stuff. Perhaps change those examples to Windows?

for 'deals with the same tag being used on multiple platforms correctly' I'm not quite sure how to update it:

    it 'deals with the same tag being used on multiple platforms correctly' do
      @confines_array = [
        {
          :platform => /^el-/,
          :tag_reason_hash => {
            'tag1' => 'reason el 1',
            'tag2' => 'reason2',
          },
        }, {
          :platform => /^cisco-/,
          :tag_reason_hash => {
            'tag1' => 'reason cisco 1',
            'tag3' => 'reason3',
          },
        },
      ]

      internal_hash = confiner.instance_variable_get(:@tag_confine_details_hash)
      expect(internal_hash.keys).to include('tag1')
      expect(internal_hash.keys).to include('tag2')
      expect(internal_hash.keys).to include('tag3')
      expect(internal_hash.keys.length).to be === 3

      shared_tag_array = internal_hash['tag1']
      expect(shared_tag_array.length).to be === 2

      platform_el_found = false
      platform_cisco_found = false
      shared_tag_array.each do |confine_details|
        case confine_details[:log_message]
        when /\ el\ 1/
          platform_el_found = true
          platform_to_match = /^el-/
          reason_to_match = /reason\ el\ 1/
        when /\ cisco\ 1/
          platform_cisco_found = true
          platform_to_match = /^cisco-/
          reason_to_match = /reason\ cisco\ 1/
        else
          log_msg = "unexpected log message for confine_details: "
          log_msg << confine_details[:log_message]
          fail(log_msg)
        end

        expect(confine_details[:platform_regex]).to eql(platform_to_match)
        expect(confine_details[:log_message]).to match(reason_to_match)
      end
      expect(platform_el_found).to be === true
      expect(platform_cisco_found).to be === true
    end
  end

We can also update it later.
