WIP - Enhancing retry logic

[Dabz]

This PR changes the retry logic of the client:

• Adding a new customizable RetryConfig to specify a custom backoff, retry count and retry timeout
• Ensuring that all gRPC calls are retried using this logic

The RetryConfig have the following parameters

• request_retry_count: int = 20 - The maximum number of retry to be performed
• request_retry_backoff_ms: int = 100 - The backoff time between each retry (exponential)
• timeout_ms: int = 30000 - The maximum amount of time to retry

The retry loop is interrupted if the number of retry exceed the defined counter or if the amount of time retrying (including the method execution) exceed the configured timeout
