Snapshots storead global sets of modules that should be replaced with vendor snapshot modules. Move the data instead to a vendor_snapshot or recovery_snapshot module type that depends on all the modules in the snapshot, and then have modules that should use the snaphsot depend on it to query for the set of modules that should be replaced. Bug: 177098205 Test: vendor_snapshot_test.go Change-Id: I2826adacfb473e9139b5ea93ba83b8a54cc1a56b
