v8 = trace

* improve error reporting in RestAqlHandler
* added logging about indexes
* added some safety checks to the logger
* slighty better error messages
* fix location header for SSL
* fix error message
* try to make tests more deterministic
* change error code from TRI_ERROR_INTERNAL (which we want to avoid) to TRI_ERROR_FAILED
* do not use V8 variant of AQL functions in early optimization stage when a C++ variant is available
* additionally, simplify AQL function definitions and aliases
* warn when more than 90% of max mappings are in use
* added C++ variant of replication catchup
* added `--log.role` option
* updated CHANGELOG

* 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
