Orphaning glacier-cli

[Miroslav Suchý]

Hi,
I just orphaned `glacier-cli` package.

It is command line utility for AWS Glacier service. I no longer use the Glacier and instead I am using B2, therefore I
am not using this package at all.
It need some love: update to recent version, migrate to python3 and I do not want to spend my time on this.

Feel free to take it if you want to.

Miroslav
