Import datasets from kaggle.com
In addition to the collections of datasets that are made available in LabPlot for easier import of data into the application, we should also support kaggle.com which seems be the central place nowadays for data sets and models used in the data science community.
Kaggle provides CLI which can be used to communicate with the online service: https://www.kaggle.com/docs/api
Our application settings dialog should be extended to handle the location of this CLI tool and of the API token. The import dialog itself should be extended to enable the search on kaggle and the actual import of the data.
