fix: Retry POST against 502, 503 and 504 responses

[kar0t]

Purpose

Retry POST against 50X responses.

Here's what I'd like to see reviewed

1. Please confirm that it is okay to handle Timeout within the POST function.
2. I am not familiar with the Ruby language, so there may be some errors. I have written it to follow the same logic as the existing faraday_get_with_retry as much as possible.

Overview

According to the trino client protocol, it should also retry for POST.

• Retry for 50X HTTP Status for GET, POST Methods #128 (comment)

https://trino.io/docs/current/develop/client-protocol.html#overview-of-query-processing
If the client request returns an HTTP 502, 503, or 504, that means there was an intermittent problem processing request and the client should try again in 50-100 ms. Trino does not generate those codes by itself, but those can be generated by load balancers in front of Trino.

Checklist

• Code compiles correctly
• Created tests which fail without the change (if possible)
• All tests passing
• Extended the README / documentation, if necessary

Please add test.

I am writing a test for the modified post_query_request!.
Will update this PR soon. Thanks for the reivew @exoego!
