Implement nested support for histograms aggregations

[waynehamadi]

Signed-off-by: Merwane Hamadi [email protected]

Description

This change allows the user to select a nested field on all histograms visualizations. This voluntarily a limited scope. I suggest we add more fields in the future. To add another field, all you have to do is change this array :
nestedAggregationsSupported = ['histogram'];
After running a query on a nested field, opensearch dashboard will automatically generate the correct elasticsearch query, send it to elasticsearch and return back nested visualizations.

From your test.txt file:

3 snapshots failed from 2 test suites. Inspect your code changes or run `yarn run test:jest -u` to update them.

Can you update the snapshots?

Thanks for the update @MerwaneHAMADI. Apologies for trying to catch up.

Just to clarify, I don't need a custom plugin for this to work? Or would it be required as mentioned in the thread.

In the thread you I see you dropped some data and referenced the legacy application. I'm trying to point this to OpenSearch and run it with 'vanilla' OpenSearch Dashboards and not seeing the same results.

If it's all working for you, could provide me with some sample data to insert and an example visualization (like the saved object if possible).

Thank you.
