feat(rpm-ostree): Add support for replacing base packages with 'rpm-o…

…stree-override replace'

This makes it possible for example to install mutter patched with triple buffering.

Looks good

@lorduskordus does this only support COPR repos? It seems odd to me that the user would provide a repo URL which is transformed into a copr-specific repo declaration. Would it be possible to support this directly with a URL?

@lorduskordus does this only support COPR repos?

@xynydev It can support other repos too, like Fedora Koji.

I see now what's the deal.
It's hardcoded to Copr repo only in the module.
Didn't think about this when reviewing the PR, my bad.

Will think about how to handle this (update docs that only COPR repos are supported until better solution comes).

In the meantime, I pushed the doc change related to this:
#280

I didn't know other repos were supported. Sorry, I wont be able to work on this, at least not soon as I have important deadlines coming up.
