ES index managment functions do not close client connection

[ahuarte47]

Describe the bug
Functions to create and delete ES indexes do not close the ES client connection:

• create_collection_index
• create_item_index
• delete_item_index

App outputs error messages to alert about this issue.

This issue occurs debugging in Windows and running in AWS Lambda. When this backend runs in AWS Lambda, create_collection_index is always invoked when starting the app, is this a severe issue?

To Reproduce
Steps to reproduce the behavior:

1. Start app
2. Invoke create_collection_index
3. End app
4. See error

Expected behavior
ES index managment functions should close the client connections.
