Summary

Changes

Introduced a new argument inside meta supportedPythonVersionthat would generate python.required in .conf and spec files while building the add-on as python.version would get deprecated in newer releases of Splunk.

User experience

For Users who would use newer version of Splunk would not have to add python.required in their .conf files manually, UCC would generate it for them if supportedPythonVersion is being defined in meta in globalConfig.
