Remove unnecessary logs of opensearchpy

[crystaldust]

The opensearchpy library will print a line of log on each request like this:

[2023-04-25, 09:01:43 UTC] {base.py:270} INFO - POST https://dev-opensearch-node1:9200/gits/_delete_by_query [status:200 request:0.006s]

Which brings huge amount of useless text, consider turn off the logs by opensearchpy settings.

Currently the opensearchpy package doesn't provide a direct way to turn it off, the only way is to get the global opensearchpy logger, and set a higher log level(higher than INFO), which is described in the issue [FEATURE] Option to turn off success logs(which is by default) #377
