Add maxRetryAttempts, connectionTimeout and readTimeout configurations

[wadahiro]

I added three new configuration options.

• maxRetryAttempts
• connectionTimeout
• readTimeout

Additionally, the default timeout is set to 10 seconds. This is because the default timeout in the Box SDK is 0, meaning it will wait infinitely. In situations where the Box API does not respond correctly, this could cause midPoint thread to be blocked infinitely as the following thread stack, so the timeout is set to avoid this issue.

Thread state: WAITING
