While maps that have numeric keys work if there is only one map with an integer key, when there are multiple maps with numeric keys in a given query, it fails.
Take the following example for a map called outer with numeric keys holding reference to another object with a map called inner with numeric keys: Updates that are meant to generate {"$set": {"outerMap.1234.inner.5678": "hello"}} are instead generating {"$set": {"outerMap.1234.inner.inner": "hello"}}, repeating the later map property name instead of using the integer key value.
This commit adds unit tests both for the UpdateMapper and QueryMapper, which check multiple consecutive maps with numeric keys, and adds a fix in the KeyMapper. Because we cannot easily change the path parsing to somehow parse path parts corresponding to map keys differently, we address the issue in the KeyMapper. We keep track of the partial path corresponding to the current property and use it to skip adding the duplicated property name for the map to the query, and instead add the key.
This is a bit redundant in that we now have both an iterator and an index-based way of accessing the path parts, but it gets the tests passing and fixes the issue without making a large change to the current approach.

spring-projects/spring-data-commons#2293 changed how PersistentProperty paths get resolved and considers potentially registered converters for those, which made the path resolution fail in during the query mapping process.

This commit fixes an issue with the pattern used for detecting $or / $nor which also matched other keywords like $floor.

This commit fixes an issue where using a simple return type leads to NPE when the actual aggregation result does not contain any values.

We now use StringUtils.replace(…) to replace the map key dot in MappingMongoConverter. StringUtils perform a plain search instead of using Regex which improves the overall performance.

Omit StreamUtils usage if input is a collection. Remove superfluous Flux.from(…). Simplify test and migrate test to JUnit 5.
