make sure CRAB job Wrapper does not use WMCore CMSSW executor

[belforte]

in particular this part about USER_TARBALL
https://github.com/dmwm/WMCore/blob/748fb8df96a9328600b254b934c8f96ced00505c/src/python/WMCore/WMSpec/Steps/Executors/CMSSW.py#L404

@mapellidario @khurtado FYI

[belforte]

CRAB stopped using WMCore CMSSW executor in August 2021
b28897e
There is no reference to $USER_TARBALL anymore
@khurtado go ahead with your cleanup and let us know when there's a new WMCore tag to check

[belforte]

If you agree, I will close.

[khurtado]

Thank you @belforte ! (and yes, the CRAB issue can be closed, I will close the WMCore issue once we remove those lines in the code)

[khurtado]

@belforte I made the following PR removing $USER_TARBALL and $USER_FILES from it.

dmwm/WMCore#11114

But I am also deleting this file and I just wanted to be sure CRAB indeed doesn't use this file at all (I couldn't find any reference here to it other than old github issues)

[belforte]

thanks for cheking @khurtado . Yes, no problem, that's not used anywhere. Looks like some old thing from pre-HTCondor times when job wrappers had to pull tarballs themselves from some central storage.

@belforte Great, thank you!
