Title: Make tests optional that depend on pydot and pandas (optional installs).

Failed on these in my amazon instance VM.

We could probably do with an "official" list of what installs developers should use?
See also https://github.com/SciTools/iris/issues/478 -- but possibly this should have gone on discussion groups instead??
