Design thoughts

I feel like the current design of dep-add and dep-upgrade is "creaking" a bit. Adding a blacklist option to dep-add to specifically omit :git/sha when upgrading dependencies feels like a hack.

Perhaps do-dep-upgrade shouldn't be using dep-add.

On the other hand:

1. I don't have any specific proposals right now, just a feeling.
2. Completely changing how dep-add and do-dep-upgrade works is a bit of work.

@borkdude This seems to be working as we want it to, though I'm not super happy with introducing the :omit-git-url option.

What do you think?

[teodorlu]

I'll fix the merge conflict.

Thanks!

Another way is to just add this dependency in your global .clojure/deps.edn profile under an alias and add this alias to your CIDER config.
