Description of problem:

• Using NFS volume claim template, and the git-clone task, the git-clone task is failing with error "could not open '.git/<path>/<tmp-file>' for reading: Permission denied" file made from the git clone command. This was tested on OpenShift versions 4.18, 4.15, and 4.16, on each version the same error was produced where the git-clone task did not have permissions to the tmp file created after cloning the repository down.

Expected results:
