Allow customization of timeouts

[Grimoren]

Error occurring during run: Command took too long to execute, try setting a higher timout: '[/bin/sh, -c, dot -Kdot -Tsvg /tmp/GraphvizJava/DotEngine7925473131433663348/dotfile.dot -ooutfile.svg]'

The plugin should have an overridable default timeout.

We might have to tell the timeout to the underlying graphviz library we're using

[SimonMarquis]

Did you try to configure the Graphviz instance directly with a custom engine with the proper timeout?

Graphviz.useEngine(GraphvizCmdLineEngine().timeout(2, TimeUnit.MINUTES))

@SimonMarquis what do you think if we provide a reasonable default lets say 30 seconds for the tasks that we create? And any one who needs more can use #183

[SimonMarquis]

The issue with this approach is that it will force everyone to use this engine.
And the Graphviz wrapper we use does rely on a default list of available engines.

Aaah I thought GraphvizEngine has a timeout as well :(

[Grimoren]

How do I access graphViz?
