Simplify the preparation for JCL testing

[std4lqi]

What It Does
Remove JCL preparation from default_properties.yaml, but have test case to check and upload test JCL when needed. This will make it easy for tester do prepare the environment (datasets and uss directories) on z/OS to run system tests.

How to Test
Run test case under __tests__/__system__/cli.

LGTM! thanks for the fix @std4lqi

@JillieBeanSim , @zFernand0 are we OK to merge it with the code duplication check failure on testing code?

Hey @std4lqi,
yeah, a lot of times we end up with some duplication due to how tests are structured.
I wouldn't worry too much about code duplication.

not sure this requires a new patch to be published.
However we can combine the contents of this PR (after merged) with:
