bug/elasticsearch connector broken on auth strategies other than username/password

[rbiseck3]

Describe the bug
When anything other than basic auth (username/password) is used, the client instantiation breaks because the username field from the access config isn't dropped, causing the following error:

TypeError: Elasticsearch.__init__() got an unexpected keyword argument 'username'

To Reproduce
Create the elasticsearch connector and set the access configs using api key data. Run check_connection() on it will reproduce this error.

Fix
To fix, all that should be needed is adding d.pop("api_key_id", None) after this line: unstructured/ingest/connector/elasticsearch.py#L69

I hit this issue as well while trying to use cloud_id and an API key. Would be great to have a fix!
