ocne image upload cannot use ~/ prefix as config path

[pfmackin]

I tried the following command and it failed. The code should be able to handle a file prefix with ~/. There is a function to resolve such a path: github.com/oracle-cne/ocne/pkg/fileAbsDir()

cne image upload --type olvm --arch amd64 --file  /Users/pmackin/.ocne/images/boot.qcow2-1.30-amd64.olvm   --config ~./.ocne/olvm-demo-cluster-config.yaml --kubeconfig $KUBECONFIG
ERRO[2024-12-20T13:49:24-05:00] open ~./.ocne/olvm-demo-cluster-config.yaml: no such file or directory 

All commands that take a config file param should be able to take ~/ prefix.
