MODE-2674 Adds the ability to pass custom Hikari configuration options to the relational db provider It configures the "minimumIdle" property to a default of 1, meaning only 1 idle connection should be in the pool at any time. It changes the structure of the WF kit by removing the custom Hikari module (which had just 1 resource) and moving that dependency inside the persistence-relational module. It also updates the Hikari version to 2.6.1.
MODE-2593 Adds datasource support to the Database Binary Store This uses the same datasource implementation (Hikari) that is being used by the relational persistent storage. This artifact has also been promoted as a top-level artifact in the WF kit.
