I found that the "Cannot change permissions is always printed even if
you have the rights to change the permissions. But anyway, I can change
permissions even if I only have read access. Check the following log
messages:

 INFO [2017-09-08 14:28:41,045] ({qtp1753447031-3709}
 NotebookRestApi.java[ownerPermissionError]:109) - Cannot change
 permissions. Connection owners [client2]. Allowed owners [client1]
 INFO [2017-09-08 14:28:41,045] ({qtp1753447031-3709}
 NotebookRestApi.java[putNotePermissions]:207) - Set permissions
 2CRXM67WA client2 [client1 ] [client2 ] [client1 ]

client1 and client2 have different roles (one is analyst the other is
user) so... I shouldn't be allowed to change the permissions.

This is on Zeppelin 0.7.1
