Extend anaconda copy to allow name & version changes

[msaroufim]

What is the idea?

I'd like to be able to download some conda binaries from https://anaconda.org/pytorch-nightly/torchserve-nightly and then promote them to https://anaconda.org/pytorch/torchserve. Version numbers for nightly scripts will include some date like 20220709 and the official release versions will look something like 0.6.0 https://docs.anaconda.com/anaconda-repository/user-guide/tasks/pkgs/copy-pkg/

So basically I'd like an extension of anaconda copy --old-name conda-forge/glueviz/20220101 --to jsmith/glueviz/0.23

But I'm not sure how to go about renaming a conda package even manually (would happily do so if an automated solution is ways out)

Why is this needed?

My team has a Github Action that takes care of uploading conda binaries for our package on a nightly basis pytorch/serve#1685

When that PR is landed we will be able to do official releases by using another manually triggerable Github Action which takes in as arguments a nightly release date to promote from and an official release version to promote to. The script will work by downloading a nightly release, renaming it and then reuploading to an official channel. This is somewhat easy to do with PyPi https://github.com/pytorch/serve/blob/master/binaries/pip/retag_pypi_binary.sh and especially easy with Docker with their docker tag

What else did I try?

I tried writing my own script which would do this change manually but the bz2 file I end up with doesn't get recognized by conda

Was asked here to put this issue here instead conda/conda#11613
