- add exception handling
- write status bad even before we start the test so we really know when
something went wrong.
* SYS exceptions will already handle system exceptions
* rethrow
* only return true if the file object has no error bit set
* don't double-close on error.
* add note that we disable exceptions explicitely

* the user or CI may now specify `--coreCheck true` if the testsuite
should perform automatic core analysis for him.

* 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

Also use different query for explain and profiling with SLEEP() for
non-zero runtimes.

* Fix runtime calculation
* Adeded a route to aardvark to export a debug dump, it can optinally contain anonymized example data

* removed not needed vars
* Added JWT token authentication and error display on debug dump button
* Fixed Error reporting on download debug dump.
* Anonymization does not anonymize system attributes any more.
* Anonymize in explainer debugDump will now anonymize bindVars and will not anonymize system document attributes.

* coordinator route stands
* stop updates in transient, when supervision off
* fix dump&restore of smart graphs (#5093)
* Added tests for dump-restore of SmartGraphs

* 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
