mgr/dashboard_v2: Add table component

The current implementation isn't finished yet, but it's a start.

The ngx-datatable is used as the core of the table component. You can
use the table to show data in a table. You can search, paginate, sort,
refresh the table contents. Multi selection is possible, the details
of the selected items will be given to the specified detail component.

What will be fixed soon?
* Enable the usage of buttons in the table header
* Enable details inline not beneath the table
* Pagination to use a input field to switch pages
* The columns to show can be checked and predefined
* The selection made by the user will be saved in the local storage
