This PR adds the get_variables_by_attributes method similar to the one in netCDF4-python and netcdf-java libraries. It is useful to filter a Dataset to known/expected attributes.

@shoyer I don't really like the docs nor the change log entry I created. I will look at them again tomorrow with fresh eyes to see if I can improve them.
