Typo in `retires` vs `retries`

[vladovarga]

Not a bug perse, but I noticed that the documentation on the client.py ( for example here https://github.com/splunk/splunk-sdk-python/blob/master/splunklib/client.py#L322 but also on the other lines in the code) and other source code files contains the keyword retires as an input param, although I believe it should be retries, correct?

Because, later in the code, the keyword retries is used and not the keyword retires as it is not mentioned afterwards anywhere esle just in the docs of classes/methods.
