Updated CHANGELOG. Clustered ShortestPath queries now require to explicitly name all Vertex Collections that can be encountered during the search in the AQL statement in order to avoid cluster deadlocks.

* AQL Breaking Chance in Cluster:
The SHORTEST_PATH statement using edge-collection names instead
of a graph name now requires to explicitly name the vertex-collection names
within the AQL query in the cluster. It can be done by adding `WITH <name>`
at the beginning of the query.
Example:
```
FOR v,e IN OUTBOUND SHORTEST_PATH @start TO @target edges [...]
```
Now has to be:
```
WITH vertices
FOR v,e IN OUTBOUND SHORTEST_PATH @start TO @target edges [...]
```
This change is due to avoid dead-lock sitations in clustered case.
An error stating the above is included.
* issue #2413: improve logging in case of lock timeout and deadlocks
* added log topic attribute to /_admin/log api
