    Update configuration field value taking into account the nesting.

    Configuration is a hash of hashes, so we need to dive inside to do proper assignment.

    E.g. _nest_config({}, "elasticsearch.bulk.queuesize", 20) will result in the following config:
    {
        "elasticsearch": {
            "bulk": {
