Rename the job category query parameters for consistency and being
able to localize those when we are going to use them as values on a
bootstrap-table filter control input element.

Introduce the jobActionButtonsFormatter function to make the code more
readable, maintainable and also reduce redundancy.

To provide the user a function to clear all column filters at once
we introduce a custom toolbar with a button for that purpose.

Introduce a range slider to select the data display range on the job
table. This replaces the old input select element to determine which
time period of data should be retrieved and displayed.

Remove the JS function updateQueryParams as it is no longer used.
