Hardcoded session timeout might fail large file uploading/downloading

Describe the bug

I was using USSFiles to upload a SMP/E package to USS. Every time, around 30 seconds after the uploading started, it failed with the following exception:

requests.exceptions.ConnectionError: ('Connection aborted.', TimeoutError('The write operation timed out'))

I didn't try Datasets but I guess it would probably fail with the same reason.

Expected and actual results

It should well support large file uploading/downloading. (...which usually takes some time to finish)

Describe your environment

• Mac, Python 3.10.20
• Zowe Python SDK v1.0.0dev26
• z/OS 3.2 on ZVDT

Additional context

I went over the implementation. The root cause seems to be at the following place:

https://github.com/zowe/zowe-client-python-sdk/blob/75ff18266f501a18ddb527aa28c1572cd7a2e8be/src/core/zowe/core_for_zowe_sdk/sdk_api.py#L60-L63

I will soon create a PR to fix this.

Inspect src/core/zowe/core_for_zowe_sdk/sdk_api.py around lines 60-63, the location identified as the source of the timeout. Reproduce a large USSFiles upload or download and verify that the hardcoded timeout no longer aborts operations that take longer than about 30 seconds.
