Introduce prefixed storage with enumeration (#4185)

Browse Source 
* Introduce storage_next allowing iteration.  (without childtries)

* Implement prefixed storage

* impl cache in client_storage_cache (needs test)

* switch overlay change to btreemap

* Revert "impl cache in client_storage_cache"

This reverts commit c91a4848916eba87184b3dc4722cea81aec9339d.

the storage cache cannot be used this way

* Revert "Implement prefixed storage"

This reverts commit 4931088126a427082d7310ed7e83b8eea966bc20.

* Impl StoragePrefixedMap for all map storages

* remove comment

* Move all overlays to BTreeMap

* btreemap iteration improvment

* impl for child tries

* impl tests for childs

* fix

* remove cache comment

* Fix grumble
