Merge branch 'master' of https://github.com/pentaho/big-data-plugin into mongoInputImprovements
Preliminary work for sampling fields/types and constructing paths.
More refinements. Array min/max index info is now displayed in a separate column in the UI. Field names are set to the last part of their respective path. Database and collection fields are now drop-down boxes that can be populated via a corresponding button.

PDI-6723: Altered constructor calls in test classes
Merge branch 'master' of https://github.com/pentaho/big-data-plugin into mongoInputImprovements
Now does the best it can in terms of data conversion for fields if the user changes the best fit Kettle type to something else. Fixed a bug where the user specified number of documents to sample was not getting passed to the sampling routine (always used 100 as the sample size). Added some unit tests.
Now only populates collections drop down when button is pressed (and not when database name changes).
Fixed bug in date handling.
PDI 8970, 8244, 8202, 7780, 8253, 7744. MongoDb input now uses latest Mongo driver and client class (MongoClient); MongoDb input now allows multiple mongo servers, connection timeouts, socket timeouts and read preference to be specified for connecting to replica sets; MongoDb input now allows the user to specify whether the query entered is a standard query or an aggregation pipeline specification; MongoDb input now has drop-down boxes for selecting database and collection. MongoDb output has had some refactoring; MongoDb output now uses the latest mongo driver and client class (MongoClient); MongoDb output now allows multiple mongo servers, connection timeouts, socket timeouts write concern "w" timeout, write concern, journaling writes and read preference (for reads performed when determining the applicability of a modifier update policy) to be specified.
Removed some old code related to setting a write concern based on Kettle logging level. This is no longer need with the new options to specify the write concern to use at design time.
