[Cloud Security][Findings++ Phase 1] Implement persistance of column order/widths

[mitodrummer]

Motivation

The 'unified-data-table' package contains callbacks to allow us to save the column layout and individual widths. Currently we store "pageSize" option in localstorage. Columns should be stored in a similar matter.

Definition of done

• Re-ordering of columns and adjustments of column width should persist between page refreshes. (local storage ok, but worth exploring other solutions)
• Logic wrt to column layout persistance etc.. should be contained within the common table component
• A "localStorageKey" or "tableSettingsKey" prop should be added to the "common table" component to allow for each table in CSP to have it's own persisted config. (each table will have a different set of columns defaults available, so we can't share column layouts between tables)
• Ensure testing happens for both ESS and serverless modes of operation
