When an image is created with a url that is in excess
of 240 characters, the transacations table in ranger
audit database throws error "sqlalchemy.exc.DataError:
(MySQLdb._exceptions.DataError) (1406, "Data too long
for column 'event_details' at row 1")". By removing
this url from the log, we prevent this error while
maintaining other important data. Also restored ranger
to allowed projects in ranger policy.json
