🚀 Feature Request: Allow non-destructive plugin slug renaming

[jdevalk]

Describe the problem that needs this feature

If we have the plugin slug fair-plugin, and want to change that to fair-connect, that currently leads to the plugin being disabled on update. We should deal with that better.

Describe the solution you'd like

1. A redirect from old-slug to new-slug.
2. The ability to update from old-slug to new-slug without the plugin getting deactivated.

This requires a change in AspireCloud too, the ticket for AspireCloud is fairpm/aspirecloud#13
