1. Added KeyValueStore.Iterate for implementing the different List, ListV2 etc. implementations. This allows for more efficient use of memory depending on the situation.
2. Implemented an inmemory teststore for running tests. This should allow to replace MockKeyValueStore in most places.
3. Rewrote tests
4. Pulled out logger from bolt implementation so it can be used for all other storage implementations.
5. Fixed multiple things in bolt and redis implementations.
* add CopyObject method
* use utils.LogClose
* extract common code from GetObject to getObject helper
* remove rr.Range from getObject helper, create helper putObject
* return rr, err in getObject helper
* extract code from PutObject into putObject helper
* remove commented out text
* remove other commented out code
* WIP trying to get storj cp command to work with copyObject
* fix typo in rb and now it works
* use rr.Size() instead of srcInfo.Size
* Revert "WIP trying to get storj cp command to work with copyObject"
