feat(quickwit): add quickwit integration

[idrissneumann]

Description

Hi. For now it's still draft but I'm exploring how elastalert2 can comply with Quickwit.

To provide a bit of context:

• I use to enjoy working with elastalert several years ago and even rebuild version for ARM32, I'm pretty convinced that it's still a relevant tool for alerting used as an external microservice
• Quickwit is one of the best log and traces search engine on the market and I'm use to contribute in order to provide integration to other opensource project (around the CNCF ecosystem) such as Falcosidekick, Odigos, and Grafana datasource for quickwit
• Quickwit has a level of interoperability with the Elastic/Opensearch API for the read query, that been said, we have to handle the mapping creation of the indexes, add a /api/v1/_elastic suffix to the URL, etc

This sounds great! I'm looking forward to trying it out.

I know this is a work in progress, but I figured I'd review it as you go to help me follow along.

No problem at all. I'm still figuring out if it's really compliant or not. For example with real test, I have this:

qw_tests-elastalert-1  | ERROR:elastalert:Error finding recent pending alerts: RequestError(400, '{\n  "message": "OneOrMany could not deserialize any variant:\\n  One: unknown field `from`, expected one of `gt`, `gte`, `lt`, `lte`, `boost`\\n  Many: invalid type: map, expected a sequence at line 1 column 206"\n}') {'query': {'bool': {'must': {'query_string': {'query': '!_exists_:aggregate_id AND alert_sent:false'}}, 'filter': {'range': {'alert_time': {'from': '2024-03-26T17:09:24.709242Z', 'to': '2024-03-28T17:09:24.709947Z'}}}}}, 'sort': {'alert_time': {'order': 'asc'}}}

Maybe @fmassot can help to see if it's something we can fix on quickwit side or not.

For the rest, I'll take care of all your feedbacks, thanks for thoses.
