Support for Optional Field names and Plugin Upgrade

[camrossi]

I have added the capability to support Optional fields as per

• Nodes data frame structure

• Edges data frame structure

Additionally in my lab/tests I was getting many errors and warning about outdated libraries and neo4j wasn't even staring (not sure why) so I ended up:

• Upgrading the Grafana SDK plugin
• Upgrading the neo4j image as well as the Grafana one

I have tried (and failed) to update the testing:

• As per the latest neo4j doc the ID field is deprecated and replaced by Entity ID
• Both ID and Entity ID are not safe to track data out of the scope of a single transaction this breaks the testing as we are comparing the IDs. see
• I have manage to fix this for runNeo4JIntegrationGraphTest by dropping the returned IDs i.e.

   nodeFrame := res.Frames[0]
   nodeFrame.Fields = nodeFrame.Fields[1:]
  
   edgeFrame := res.Frames[1]
   edgeFrame.Fields = edgeFrame.Fields[3:]
  

however I can't understand how to do the same for the runNeo4JIntegrationTableTest I spend hours trying and I just can't get it to work... as mentioned in the issue I just learned go so I did the best I could...

I have tested this PR with Grafana v11.3.0 and it is working as expected:

Here an example where I am setting 'mainstat'

Edit: I know I need to un-do the changes in the CICD files !
