Link progress bars to their respective sink overview

Problem / Motivation

List of batched jobs (progress bars) is present on the sinks overview page, but there is no easy way to enter the sink's landing page.

Suggested resolution

Make the progress bars linked to their respective sinks.

There is no simple link between batches and their sinks. Batch jobs initiated as sink operations simply kicks off a new batch with batch name as the only vaguely identify-able property to determine what sink is behind it.

To do this properly we need a sink <-> batch map, populated on batch dispatch.

To do this quick'n'dirty, we split the batch name by : and assumes the sink ID is the part before ':'.
