folio-testing down and snapshot not updated due to update to mod-vendors interfaces

The folio-testing environments (Vagrant and AWS) failed to build overnight 25-26 January due to a major overhaul of the interfaces provided by mod-vendors (https://github.com/folio-org/mod-vendors/pull/43), which caused sample data loading to fail. Resolution will be multi-part:

• Build the folio-testing environments without mod-vendors sample data. This should result in a successful build, but presumably ui-vendors will not work (since it still requires the old vendor inteface)
• Work with mod-vendors dev team to load new sample data, either via the API or through tenant initialization (see FOLIO-1519)
• Work with ui-vendors dev team to coordinate changeover from old to new mod-vendors, so that snapshot environments will continue to build smoothly.
