Summary
Avoid potential race conditions between file and metadata upload in, for example, Cloud Functions that are triggered by file upload and rely on certain metadata being immediately present on those files.

This potential problem was brought to light in this issue: https://github.com/aerosense-ai/data-gateway/issues/87.

Fixes
- Add metadata to blobs before uploading to cloud storage

<!--- END AUTOGENERATED NOTES --->

Summary
Use signed URLs to point to cloud datasets in input manifests when sending them to children for processing. This means the children will always be able to access the input datasets - not just in the special case of the parent and child having access to the same buckets.

Fixes
- Use signed URLs when sending input manifests to services

Refactoring
- Factor out dataset URL signing to new `Manifest` method

Testing
- Simplify service tests' arguments
- Update test method docstring
- Ignore irrelevant files in test
<!--- END AUTOGENERATED NOTES --->

Summary
Allow metadata from datafiles instantiated from signed URLs to be retrieved. This has been tested with the real Google Cloud Storage endpoint and works in production, but doesn't currently with the storage emulator used in our tests. See 489 for more information.
