If all the specific cleaning param: hoodie.cleaner.commits.retained, hoodie.cleaner.hours.retained, hoodie.cleaner.fileversions.retained all have detemistic policy, then this option should be eliminated.

The reason I keep `hoodie.cleaner.policy` is that we should still make it backwards compatible, so that if `hoodie.cleaner.policy` is set, we should honor that. If none of `hoodie.cleaner.commits.retained`, `hoodie.cleaner.hours.retained`, or `hoodie.cleaner.fileversions.retained` is set, the specified policy should be used, and the default clean config value (commits, hours, or file versions retained) is used.

   Makes sense.  Fixed.
