Base layer doesn't have upgrade-charm hook

I see the base layer doesn't include the upgrade-charm hook. What is the reason behind this? I think it should be included in the base layer since the idea is that every Charm will have one.

I agree. You could, of course, create a regular upgrade-charm hook, but I think it would be useful to have it use the reactive pattern if only to easily enable multiple layers to perform actions on upgrade.

However, the basic layer isn't technically part of charm-tools, so I've re-opened this issue on the (new) basic layer repo mentioned above.
