/**
* The buildQuery function is used to create an instance of QueryContext that's
* sent to the chart data endpoint. In addition to containing information of which
* datasource to use, it specifies the type (e.g. full payload, samples, query) and
* format (e.g. CSV or JSON) of the result and whether or not to force refresh the data from
* the datasource as opposed to using a cached copy of the data, if available.
*
* More importantly though, QueryContext contains a property `queries`, which is an array of
* QueryObjects specifying individual data requests to be made. A QueryObject specifies which
* columns, metrics and filters, among others, to use during the query. Usually it will be enough
* to specify just one query based on the baseQueryObject, but for some more advanced use cases
* it is possible to define post processing operations in the QueryObject, or multiple queries
* if a viz needs multiple different result sets.
