Add a new property to the LogEntry class that describes the resource where the log entry is (or will be) stored

Is your feature request related to a problem? Please describe.
Today we have an ability to set log name to project based log location only (see logName field in LogEntry for more information).
The ability to provide billing, organization or folder based log resource name is missing.

Describe the solution you'd like
It would be great to define functionality which will help to provide these values (custom project location) per LogEntry instance.

Describe alternatives you've considered
None - as mentioned before today only project based location can be set.
