Implement record maintenance screen for administrators

[andrewbrazzatti]

Currently there isn't a dedicated screen for administrators to be able to view all the records in the system for maintenance and reporting purposes.

The existing researcher centric screens work from a research data DLC perspective and where a person isn't expected to have many records of any particular type (e.g. less than 100) but are not easy to use if you need a more universal view of the system.

A data grid component such as ag-Grid should provide a rich interface that will allow searching, filtering and also exporting.

Potentially we may be able to allow batching functionality as well from this screen.
