[MS-632] [API] Update connector retry mechanism with tenacity library. Remove allow_retries

[imda-lionelteo]

Description

Update retrying mechanism and making user experience better

Motivation and Context

While doing the unit tests for the connector endpoints, there are some key, values that are redundant.
This ticket addresses the following to make user experience better:

1. Remove allow_retries and num_of_retries in replacement for a key max_attempts.
   With max_attempts it automatically defines if retries is necessary or not.

2. Replace the naive implementation of retrying with a library that can provide other forms of retries (retries with jitter and others). The library to be used will be tenacity.

3. Moving model attribute which is part of the optional params to a necessary attribute, but the key may be optional.

Type of Change

• feat: A new feature

How to Test

Run unit-test or run a cookbook/recipe run
