* forward-port AQL optimizations from 3.3
* fix restrict-to-single-shard rule
* added tests for specific cases
* ModificationNodes now can know if they are restricted or not
* OptimizerRule now updates the ModificationNode instead of setting ownName on remote node.
* The DBServerEngine container now only sends a subset of snippets (those which are relevant) It is able to restrict any part of the query to a certain shard or even a list of shards
* ExecutionEngine CreateBlocks in ClusterMode now returns Result instead of throwing.
* Adapted Coordinator side to a bitter mapping of RemoteNode => QuerySnippets. This is still ongoing work.
* Fixed Coordinator enginecontainer test and finisehd implementation of EngineInfoContainerDBServer. Seems to work so far, need to adapt test to prove it.
* Adapted test for modification nodes and restrict to shard.
* restrictTo can now be de-/serialized on Modification Nodes
* Fixed Community Compile Error
* Added a test for Indexes/EnumerateCollection nodes
* EnumerateCollection and IndexNode now have options to be restricted to a single shard, opt rule not yet updated
* DBServer part of planning now checks Enumerate and IndexNodes for single shard optimization
* Added tests for simple single shard optimization on IndexNodes
* Adapted optimzierrule for SingleShard optimierung on IndexNodes
* Fixed an issue with externally restricted shard ids in combination with shard_id based optimization
* Added a test for multiple single shard optimizations on the same collection
* Removed collection/Shard duplicate check of optimize to single shard rules
* Updated Explainer to handle optimize to single shard
* Let more tests pass an optimized AQL variant
* Temporarily disabled a tests that can only be solved after some work in transaction
* fix dump&restore of smart graphs (#5093)
* Added tests for dump-restore of SmartGraphs
* Arangosh will now expose isSmart and the smartGraphAttribute on properties
* RestReplicationHandler will now ignore smart-graph collections unless you execute it with force
* Added changelog
* Reactivated original mmfiles dump/restore test
* Skip hidden smart graph collections in arangodump
* Do not dump shadowCollections metadata of smart edge collections
* Cluster optimizer rules for soerted gather nodes now handle virtual edge collections correctly
* Added a dump/restore tests for smartgraphs in rocksdb as well
* Deactivated checks for writesExecuted statistics in dump/restore tests for smartgraphs mmfiles
* Really exclude shadowCollections
* Reduced loglevel
* Added tests
* Don't change single-server behaviour
* Fix tests for omitted shadowCollections and hidden collections
* Activated statistics in MMFIles dump test again and included isEnterprise in rocksdb dump test
* A modification node can now disableStatistics, which means it does not contribute to query->extras() this is only relevant in SmartGraph case so far.
* Added a test to dump&restore satellite collections
* Bugfix: restore satellite collections properly
* Added regression test for internal issue #2237
* Fix bug #2237
* Updated CHANGELOG
* Copied dump/restore tests to rockdsb
* Removed enterprise test
* Added inline comment for smart-edge collections in optimizer rules
* Removed duplicate CHANGELOG entry
* Simplified removal of shadowCollections
* fix jslint
* Made internal.isEnterprise() available in js client context. Taken from 3.3/59f655fa
* fix broken dump_encrypted test
* Removed accidentally copied CHANGELOG entry
