[editor] Auto-created oozie schedule WF docs can raise permissions exception for shared users

Since we now create an oozie workflow document ("Schedule of...") when we save or run any Hive query, a user that opens a shared document will run into a permissions exception in Oozie decorators:

File "/Users/jennykim/Dev/hue/apps/oozie/src/oozie/decorators.py", line 69, in decorate
doc2.can_read_or_exception(request.user)

So these auto-created WFs need to either inherit the permissions of the dependency documents, or we need to somehow bypass the permissions check of the WF doc for shared documents.
