MLE-23230 Trying out retry interceptor

[rjrudin]

This is a prototype; we don't want to apply it automatically. Intent for now is to see if this helps avoid connection errors during the regression piplines in Jenkins.

Pull Request Overview

This PR introduces a prototype retry interceptor for the MarkLogic client API to handle connection errors during regression pipeline testing in Jenkins. The implementation adds automatic retry functionality with exponential backoff for certain types of network failures.

• Adds a new RetryInterceptor class that implements OkHttp's Interceptor interface
• Integrates the retry interceptor into the client builder with default retry parameters
• Implements exponential backoff with configurable retry attempts and delay bounds

When InterruptedException is caught, the thread's interrupt status should be restored by calling Thread.currentThread().interrupt() to properly handle thread interruption.

Suggested change

	logger.warn("Ignoring InterruptedException while sleeping for retry delay: {}", ie.getMessage());
	logger.warn("Interrupted while sleeping for retry delay: {}", ie.getMessage());
	Thread.currentThread().interrupt();

This line is unreachable because the for loop will always either return a successful response or throw an exception within the loop body. The lastException will never be null when reaching this point.

Suggested change

throw lastException;
