Is your feature request related to a problem? Please describe.
Recently we introduced an ability to add a new property to the LogEntry class that describes the resource where the log entry is (or will be) stored. This solution introduces a new problem, when log deletions cannot be done for non-project base log destinations since delete log functionality today uses only project bases resource names.

Describe the solution you'd like
Add an ability to delete logs based on additional parameters like custom project, folder, organization or billing account resource names.

Describe alternatives you've considered
None.

Additional context
