Delete object doesn't check conditions

[kvrhdn]

Hi, thanks for this project, it's been really helpful for us!

I noticed that conditions are not checked when you delete an object. When we create or update objects conditions work as expected.

I'm sending a request with an invalid version 123:

DELETE /storage/v1/b/tempo/o/overrides%2Fsingle-tenant%2Foverrides.json?alt=json&ifGenerationMatch=123&prettyPrint=false

This request should fail but it succeeds with a 200 and deletes the object.

Digging through the code it seems storageFS.DeleteObject does not pass in conditions:

fake-gcs-server/internal/backend/fs.go

Lines 379 to 391 in 4f69521

	// DeleteObject deletes an object by bucket and name.
	func (s *storageFS) DeleteObject(bucketName, objectName string) error {
	s.mtx.Lock()
	defer s.mtx.Unlock()
	if objectName == "" {
	return errors.New("can't delete object with empty name")
	}
	path := filepath.Join(s.rootDir, url.PathEscape(bucketName), objectName)
	if err := s.mh.remove(path); err != nil {
	return err
	}
	return os.Remove(path)
	}

Would the solution be as simple as passing in the Conditions and checking them like you do in CreateObject?

fake-gcs-server/internal/backend/fs.go

Line 199 in 4f69521

func (s *storageFS) CreateObject(obj StreamingObject, conditions Conditions) (StreamingObject, error) {
