* Added some comments on condition, renamed variable as suggested in review

* Added check for min replicationFactor to be non-zero

* Added assertion

* Added function to modify min and max replication factor in one go

* added missing semicolon

* rm log devel

* Added a second information to follower info that can keep track of followers that have been in sync before a failover has taken place

* Maintenance reports previous version now to follower info. instead of lying by itself. The Follower Info now gets a failover save mode to report insync followers

* check replFactor against nr dbservers

* Add lie reporting in CURRENT

* Reverted most of my recent commits about Failover situation. The intended plan simply does not work out

* move replication checks from logical collection to rest collection handler

* Initial commit, old plan, does not yet work

* fixed ires tests

* Included FailoverCandidates key. Not fully implemented

* fixed wrong assert

* unified in sync follower reporting

* fixed compiler errors

* Cleanup locking, and fixed potential deadlocks

* Comments about locking order in FollowerInfo.

* properly check uint

* Keep old leader as potential failover candidate

* Transaction methods now use followerInfo to check if the leader can write, this might have the sideeffect that 'failoverCandidates' are updated

* Let agency check failoverCandidates if possible

* Initialize member variables

* Use unified follower reporting in DBServerAgencySync

* Removed obsolete variable, collecting it somewhere else

* repl factor attr check

* Reimplemented previous followers, second attempt now. PhaseOne and PhaseTwo can now synchronize on current.

* Fixed assertion, forgot an off-by-one

* adjusted test to be more preciese now

* Fixed failove candidates list

* Disable write on dropping too many followers

* Allow to run updateFailoerCandidates multiple times with same leader.

* Final fixes, resilience tests now green, crossing fingers for jenkins

* Fixed race on atomics comparison

* Fixed invalid number type

* added nullptr handling

* added nullptr handling

* Removed invalid assert

* Make takeover of leadership an atomic operation

* Update tests/js/common/shell/shell-cluster-collection.js

* Applied review fixes

* There is no timeout

* Moved AQL + Pregel to INTERNAL_AQL lane, which is medium priority, to avoid deadlocks with Sync replication

* More review fixes

* Use difference if you want to compare two vectors...

* Use std::string ...

* Now check if we are in recovery mode

* Added documentation for minReplicationFactor

* Added readme update as well in documenation

Bug fix/create collections better preconditions (#9296) 
* Fixed case where a SmartVertex collection could be available too early. Only possible if a SmartGraph is created only with this one collection.

* Now the TTL remove operation will properly check preconditions again.

* Second attempt, we only  say collection creation was success iff the plan for the collection has not been mdified during create.

* Disabled assertion in favor of tests.

* Removed debug output

Bug fix/collection babies (#9124) 
* Bug fix 3.4/collection babies (#9033)

* Prepare API to create multiple collections in a single request to ClusterMethods to improve speedup

* Added counter on how many collections are successfully created

* Allow multi collection creation one level higher

* CollectionMethods now allow batch createion of Collections

* Improved array size assertions

* Now a graph is createad within a single roundtrip in the agency.

* Added new header files

* Insert collections in the AGENCY with TTL and a isBuilding flag, collections with this flag should not be visisible in the coordinator

* Added forgotten C++ file

* Fixed a rare race condition, and the failing IResearch Tests

* readded callback on DONE, otherwise lists are out of sync

* Fixed assertions to let mocked tests pass...

* Fixed community cluster

* Started fixing IResearch analyzer test, catch-tests are failing ;(

* Solved missed merge-conflict

* Added helper functions in AnalyzerFeature-test

* Refactoring AnalyzerTest Section-Auth

* Refactoring AnalyzerTest Section-Emplace-Duplicates

* Refactoring AnalyzerTest Section-Emplace-Error-Cases. Recovery-Test is now red, it seemed to be green because of invalid test case before.

* Refactoring AnalyzerTest, split GET test into multiple parts, still left 'cluster simulation'.

* Attempt to extract Coordinator / DBServer tests a little bit. This commit starts to break all Coordinator tests. However i am convinced that earlier version did NOT test a cluster situation at all, but some hybrid of SingleServer with full local storage that got told to be a Coordinator from now on, but without any Coordinator setup...

* Temporarly disabled some tests in AnalyzerFeature, as discussed with @gnusi.

* Fixed include guard.

* Temporarily deactivated failing tests

* You shall save your files before you commit...

* Fixed test asserting on plan version, which is now higher than before
