* Added AQLPhase to the affected features
* Added ServerPhase to Features
* Added FoxxPhase to the relevant features
* Added AgencyPhase to the relevant features
* Moved registration from local variable SYS_SYSTEM_REPLICATION_FACTOR from cluster to V8 as their ordering is now vice versa

* Removed merge conflict
* Moved ReplicationTimeout into cluster phase and fixed cross-phase requirements
* Added greetings phase. This phase separates the Basics Phase and is the first to be run. Includes Logger and Hello/Goodbye
* Added the GreetingsPhase in the corresponding features. Now all BasicsPhase features start after greetings Phase. There is some issue in this branch which prevents the Agency from Gossipping right now. Will be fixed next

* Modified header to new initializeCursor API
* Adapted initializeCursor to DONE/WAITING API. Compiles but not tested and no one reacts to WAITING state, it is not returned anywhere yet
* Subqueries now expect a WAITING return from initilize cursor. However they will just return a nullptr and pretend the query is empty, this will be fixed later
* First attempt to simulate thread waiting over information within the query
* Small fix to allow for isDirect handlers to go to sleep.
* Waiting in the necessary places now for the async request to be send.
* Thank you auto-casting compiler, you are totally right i absolutely wanted to use this bool value as an index in may Array. How could i possibly not want to use it here?
* Include cond-var header

* Non-compiling intermediate commit for handover.
* Make branch compile again
* Started implementation of continueable rest cursor handler by moving the callbacks to the outer part. This is not yet fully tested!
* Made finalizeExecute noexcept. We cannot react to this errors as the response was potentially written before. Also introduced continueExecution in the RestHandler engine.
* First successful query wakeup.
* The wakeup callback now posts on the scheduler directly. A resthandler only needs to provide a callback that encapsulates the continueExecution call on this handler
* renamed finalizeExecute to shutdownExecute
* Added a differentiation between Handler and Callback in Query continuation. Handler will be posted in IO service. Callback will be executed directly
* fix audit log
* Removed callback from deleteQueryCursor. This cannot be waiting
* use CONDITION_LOCKER
* removed yet another thread-local variable
* Fixed forward declaration
* Made RestAqlHandler repeatable
* Use defer to close the query in RestAqlHandler. Now waiting will close the query as well.
* Added a mutex in the RestHandlers to make sure if the callback over network is too fast that there is only one Thread running in the RestHandler
* Captured the GeneralCommTask if it is posted to a RestHandler. This is necessary in the PAUSED case
* Refactoring of _noLockHeader responsibilities. Now the BaseHandler selects them and resets them after it is done. Only Coordinators are allowed to define them if a query is loaded.
* Removed reaction to existing nolockheaders in Coordinator Query Planning Phase
* Removed incorrect assertion.
* Further refactoring of NoLockHeaders. Now there is a wrapper class around it which allows for debugging and logging. The state now seems to be better. Also all non-rest-handler triggered queries clean up the NoLockHeaders properly.

* Swing to the Symphony of Destruction
* Forgot about community build...
* Fixed compiling of Catch tests
* Fixed community build
* need thread for size

* Added two profiler tests for filter
* Avoid too many getBlock calls in the FilterBlock
* Removed debug output
* RemoteBlock API will now send a done(bool) flag whenever we request documents from remote Servers. It is possible that we are DONE and have a result. The pre 3.4.0 API uses exhausted which is exclusive to a result. This API is still implemented for beckwards compatibility.
* Implemented an executeSync function in AqlQuery. This will block the thread until query execution is complete
* Added another test for FILTER, and one test for the HashedCollectBlock
* Added more tests for HashedCollectBlock; avoid unneccessary getSome calls
