Added async-retry package for agent spin-up retries

[KulkarniShashank]

What?

This pull request adds the async-retry package to the project, allowing for multiple retry attempts when attempting to spin up the agent. This enhancement aims to improve the agent's robustness and reliability by handling scenarios where the agent spin-up fails.

Why?

In certain situations, the agent spin-up process can encounter transient errors or issues that might be resolved with subsequent attempts. By introducing the async-retry package, we can implement a retry mechanism that will help increase the chances of successfully spinning up the agent, even when initial attempts fail.

How?

• The async-retry package has been added as a dependency to the project.
• A new function/method has been introduced to encapsulate the agent spin-up logic, which includes the retry mechanism.
• When the agent spin-up process encounters an error, the async-retry package is used to automatically trigger a specified number of retries with customizable delays between each attempt.
• Detailed logging has been added to capture the retry process and any relevant error messages, aiding in debugging and monitoring.
• This enhancement contributes to a more resilient and reliable agent spin-up process, reducing the impact of intermittent issues and increasing the overall stability of the system.
