The addition of the logger requires several updates to tests to deal with the possible warning, or muting if there is not way to specify an allowed (but not mandatory) warning
* Adjusted integration tests to use geoip test fixture or to use test databases provided via config dirs (for qa module / docs).
* Kept the geolite2-databases dependency for most of the unit tests only.
* Made fallback_to_default_databases parameter on geoip processor a noop and emit deprecation warning upon using it.
* If no geoip databases are available yet to a node then the geoip processor factory returns a processor implementation that flags documents that databases are unavailable. This allows these documents to be reindex later with a pipeline. These documents will have a tag string array field, which contains a string _geoip_database_unavailable_{database_name} for each missing database in a pipeline.
* Added reload pipeline capabilities is IngestService, so that when databases are available again on a node then pipelines with geoip processor definition can be reloaded.

In https://github.com/elastic/kibana/pull/113783, we renamed Kibana's **Ingest Pipelines** feature to **Ingest Pipelines**. This updates screenshots and references for the feature. It also replaces a few remaining `ingest node pipeline` references.
