##### SUMMARY
When installing a collection, all files are created with mode 0600. This is caused by the way the collection .tar.gz file is extracted: https://github.com/ansible/ansible/blob/d3ec31f8d5683926aa6a05bb573d9929a6266fac/lib/ansible/galaxy/collection.py#L1076-L1090 The file created by `tempfile.NamedTemporaryFile()` seems to have mode `0600` and is simply moved to the final destination without a following `os.chmod`.
