* remove API docs for endpoints that were deleted in 3.0
* remove unused variable
* set all scalar values in the ctor, so check tools do not complain
* move Result objects
* prevent potential nullptr access
* remove ambiguous boolean parameter with no clear meaning
* make code check tools happy
* don't allow copying cache Findings, allow moving Results
* the debug functionality for counting RocksDB key ranges was broken
this produced sporadic test failures
* remove superfluous iostream include
* fix range checks
* don't leak if an error happens during database removal
* try to simplify Result a bit
* try to deletion checks a bit more robust
* Augmented cache API and fixed a potential deadlock scenario.
* The RocksDBEdgeIndex now tries to read up to 10 times form the cache on lock_timeout. Instead of rewriting everything after first attempt
