[FEA]: Make graphviz rankdir configurable

[nvawood]

Is this a new feature, an improvement, or a change to existing functionality?

Change

How would you describe the priority of this feature request

Low (would be nice)

Please provide a clear description of problem this feature solves

I want Morpheus to support changing the direction of Graphviz pipeline images, because I find longer pipelines difficult to visualize in a left-to-right format.

Describe your ideal solution

A new command line parameter that sets the rankdir argument.

@click.option('--viz_direction',
              default="LR",
              type=click.Choice(["LR", "TB", "BT", "RL"], case_sensitive=True),
              help="Set the direction for the Graphviz pipeline diagram.")

pipeline.visualize(kwargs["viz_file"], rankdir=viz_direction)

Describe any alternatives you have considered

@nvawood rankdir can currently be configured if you use the Pipeline.visualize("my_file.png", rankdir="TB") method. Does this satisfy this request or do you need it part of the CLI?

[nvawood]

I think if it's going to remain an option in the CLI, then it should be configurable there as well.
