Entitled users can send the generated file to the ArangoDB support to facilitate
reproduction and debugging.
The data from the generated file can be restored and analyzed via the *inspectDump*
function:

* multiple cluster-related AQL optimizations
* do not apply single-shard optimization if _includedShards is already set from the outside
* implement changes requested by @mchacki
* reduce extractions to projections
* recycle string buffers in SocketTask
* micro optimizations for mmfiles indexes
* added special lookup function for _key
* moved function into the correct file
* speed up key buffer allocations a bit
* added noexcept specifier
* correctly name variable
* explicitly move bounds
* fix and speedup from/toPersistent functions
* reuse string from ManagedDocumentResult for multiple lookups
* use move-assign
* a bit less work for single server
