Allow Segments to define multiple SQL columns if the segment value can be matched in any of those fields, and use to define two new segments: customVariableName & customVariableValue.

Moved processed metrics computation to DataTableGenericFilter, removed new filters & implemented as methods in Report to avoid confusion regarding re-use, allow adding processed metrics as DataTable metadata and use this to rewrite AddProcessedMetrics filter, correct name of Metrics::getMappingFromIdToName function, added placeholder AggregatedMetric class for future, revise Metric/ProcessedMetric hierarchy (add methods for translation/etc.), allow .get API methods to use metadata to automatically figure out which columns to select, get EcommerceOrderWithItemsTest to pass.

This is using the Custom Variables per page, using slot 3/4/5 to track sku/name/category

 * Items reports (best SKU/Name/Category) will automatically call the Custom Vars API and enrich the items reports with "Visits", "Conversion rate"
 * Updating integration tests + fixing bug when item is deleted from Cart, then added again (or purchased)
