Mirrors in uberenv cannot be defined with an url (http or oci)

[adrienbernede]

The mirror concept in uberenv is currently bound to mirrors for packages source tarballs.

If an url is passed:

• if it starts with https: uberenv will not check that the path exists, but uberenv will try to create the mirror and push the tarballs to it.
• if it starts with oci: uberenv will check make that an absolute path...

Desired behavior:
For now, I don’t need anything specific, but I found it worth noting (documenting ?).
What I miss, essentially, is a way to stop uberenv after the environment was created, but before anything is installed, so that I could configure a binary cache into it on command line.
I may be able to just define my binary cache in the spack.yaml directly.

We do have an option --setup-only. Does that help?

--setup-only stops before the environment is create. I need to stop after the environment is created, so that I can customize it before installing.

hmm.. thought it did but honestly was rushed and didn't check. Guess we need a new option...
