Can someone share a .services.yml entry for the use of ElasticsearchHandler

Hey bud, here's what I did.
1. In `parameters` section of services.yml:

  monolog.channel_handlers:
    default:
      handlers:
        - name: 'elasticsearch'
          formatter: 'elasticsearch'
        - name: 'rotating_file'

(Yes, that means I'm routing to Elasticsearch _and_ a local rotating file - this is my local environment so I wanted some double-coverage as I played with log levels)

2. In `services` section of services.yml:

services:
  monolog.handler.elasticsearch:
    class: Monolog\Handler\ElasticaHandler
    arguments: ['@elastica.client', {'index': 'brandname_local'}, '%monolog.level.notice%']
  elastica.client:
    class: Elastica\Client
    arguments: ['http://elasticsearch:9200']
    # arguments: ['https://vpc-test-logging-an_aws_instance_name_here_for_testing_remote_logging:443']

(I have a commented out argument for the hostname with port so I can swap from logging to a local instance of ES vs an AWS instance)

I think the thing missing from your comment was the `elastica.client` that your handler needed to reference. I tried with the elasticsearch.client but that needed an additional `resolver` and boyo that went down a failure rabbit-hole.

I configured ElasticsearchHandler inside service.yml file. Kindly review this patch file.
