* Massive refactoring. Made Factories for graphs to make SmartGraph much more transparent. Also reduced amount of multiple implementations of the same stuff. Killed vocbase/graphs use GraphManager instead. Removed usage of GraphCache, was not completely implemented anyway and only partially used, which is bad at the moment. Option for later improvement never the less

* Client Graph API now correctly sends `orphanCollections` and not `orphans`
* Let GraphOperations modify the graph in-place. It should now properly handle edgeDefinitions.
* Added initial cid StaticString
* Included the vocbase in fromPersistence creation of Graphs. Only required to enhance 3.3 SmartGraphs on the fly.
* Fixed internal error message
* Fixed compiler isses originiated from merging
* Removed unused imports
* Regenerated generated file
Next steps after DC2DC and Cluster doc improvements:
- We refactor replication sections and make more intuitive separation between Master/Slave and the new Active Failover in 3.3
- We create corresponding sections for Master/Slave and Active Failover in the Administration and Deployment chapters, as well as in the Scalability chapter, where these "modes" are introduced
- We touch and improve the "Architecture" chapter as well, where some architecture info have to be placed
- We reorg the TOC having in more "logical" order:
-- Deployment
-- Administration
-- Security
-- Monitoring
-- Troubleshooting
- We adds parts in the TOC
- We add toc per pages, using page-toc plugin
- We also put close together "Scalability" and "Architecture" chapters, preliminary steps of further improvements / aggregation
- We improve swagger
