Bug Description

Right now we get raw DOT graph in fuelclient. There is a lot of connection between tasks that makes a lot of noise.
To improve readability we should add option to process whole graph with "tred" [1] (if Graphviz is installed)

Results before and after can be seen in attachments.

Can be safely moved to 8.0 because it is feature.

    Add transitive reduction filter for task graphs

      Remove 'pydot_ng' that doesn't support transitive reduction filtering.
      Add '--tred' option for CLI.
      Usage example:

          fuel graph --render graph.gv --tred
          fuel graph --render graph.gv --dir ./output/dir/ --tred

Update

On CentOS fuel graph --render completely broken because it required pygraphviz library, which cannot be installed on CentOS
