updated retry_time

[Kyoshiin]

Why are these changes needed?

Getting an error message that says "Please retry after 59 seconds", but FLAML was retrying in 10-second intervals.

Changed retry_time in flaml.oai

- retry_time = 10
+ retry_time = 60

Closes microsoft/autogen#14

I believe the feature wanted is to increase the retry time interval if the error message suggests a larger interval. @ekzhu Please advise.

Thanks for the pull request! It looks like it is changing the retry intervals directly. Is there a dynamic way to set the retry interval based on the error message?
