Improvements to WFS indexing: dashboard and map widget

[jahow]

This PR adds a little polish to the WFS indexing system:

• a list of ongoing indexing jobs is now available in admin/dashboard
  This is still very raw data, taken directly from the ElasticSearch index. We will have to make a more robust system in the future with start/stop controls and finer status (hint @fxprunayre).
  

• fix for WFS indexing not working #2498

• bonus: a functional heatmap (backported from a customer fork):
  

Still a lot more to do on this topic, both on the frontend and backend, but hopefully this PR will make the system a bit more suitable for basic use.

Would it make sense to move that to the harvesting section as this is about harvesting remote content ?

Why not, the reason why I didn't do that is because to me this is more about indexing than harvesting (i.e. replicating a dataset).

Also, as I understand it, the Status interface is generally used for monitoring activities (regular visits to make sure everything works as intended), whereas the Harvesting interface is more of a setup one, where the user might go a few times to adjust settings and then leave it alone.

At any rate, moving this view should be virtually effortless.

Good day, I am using Geonetwork 3.10.4 and elasticsearch 7.9.2 and I have the same problem, I can't use the wfs filter, i can fixed the remote index error in dashboard status "Remote index module is not installed in your catalogue installation. Add 'es' to the spring.profiles.active in WEB-INF/web.xml to activate it", but i can't use the wfs filter. I am not a developer, i am a single user, but this situation is too difficult, please I need some help. I used tools in dashboard "(beta) remote index and i received this error "IOException and i receive this error:
