[DAR-4071][External] Full cycle E2E test

[JBWilkie]

Problem

Changes to the schemas of Darwin JSON 2.0 & the properties manifest file have historically caused some import issues in the past, and we haven't had a way to detect them

Solution

This PR adds a "full-cycle" E2E test. This means:

• 1: Register a set of files from external storage to a dataset
• 2: Import some annotations
• 3: Create and pull a release of the dataset
• 4: Delete all items from the dataset
• 5: Push and import the pulled files & annotations to the dataset
• 6: Delete locally pulled copies of the dataset files
• 7: Create and pull a new release of the dataset
• 8: Assert that the pulled data is as expected

Changelog

Improved E2E test coverage
