Proposal: `meta.upgradeGroup`

From NixOS/nixpkgs#493379 (comment)

COSMIC DE uses update scripts to update each of the initial components, but does not use @r-ryantm because each of the components should be updated simultaneously.

I propose the addition of meta.upgradeGroup, which is a string that if present, requires that all other packages with the same meta.upgradeGroup also be updated at the same time.

Same boat, but wondering if toggling on passthru.enableBulkUpdates (or whatever else to call it) would ensure that all packages maintained by a specific lib.teams.${team} all get updated together.

Just my two cents. But I'm open to anything as well as long as we get bulk updates.

I think it's entirely plausible that at some point the COSMIC team might end up with ownership of something that is updated separately from the rest of the stuff. Additionally, it'd be nice to not require the creation of a new team to use this feature.

For COSMIC it doesn't seem like a big deal to do updates manually. But there are many instances where a package has to be updated at the same time as a library it uses.
