* coalesce options `bucket` and `getKey`
this is a breaking change!
also:
- remove `req` because it's an internal, unstable api that might change any time and should not be used directly
- use an params object for getKey/bucket functions instead of positional arguments, to make it more clean, and easier to add more data in the future
- add metadata to `bucket` whenever we are aware of it
* fix lint
* Apply suggestions from code review
