Add icons for region and provider to data plane labels #1781
Description
Could we please add flag icons to represent region, and provider icons to data plane labels (Admin->Settings screen, dropdown on new task creation, and on connector overview page)
For context we continue to get some customer confusion (US customers selecting our EU public data plane because they wanted AWS), and we've just added a new data for AWS US East and US West so there are now more options we want customers to understand + choose between.
