Add an OpenSearch destination plugin

I restarted this from scratch as there was a lot of duplication between the elastic search and open search modules.

I added a base module called data pipelines search base and had both modules extend that, the result is a lot less code.

Here's a patch for that (the do not test patch) that is against 🐛 Timeout when processing large files Fixed as well as a full patch that includes 🐛 Timeout when processing large files Fixed

Need require-dev entry for opensearch

Re-roll now the other issue is in

Why not ^2.2?

Needs a reroll.

I think we can combine #3269883: Move elasticsearch field mappings from data pipelines plugin to elasticsearch destination plugin → with this issue as well.
