This change sets the Faraday adapter used for ElasticSearch to `:net_http`.
The `elasticsearch-transport` gem tries to auto detect a suitable Faraday
adapter. Mastodon uses the Faraday default adapter of `:net_http`, but since
`elasticsearch-transport` sees that the `httpclient` gem is available it lets
Faraday use that one. Unfortunately `httpclient` does not properly clean up
its connections, leading to a lot of established connections to ElasticSearch
over time.
