Remove all cache entries for a particular plugin
### Feature Description

In the UI under "Homebridge Settings" you can either delete one accessory from the cache or all accessories from the cache.
What would be useful for would be to be able to delete ALL accessories for a particular plugin from the cache. This is particularly helpful when developing new plugins, and for delivering updates to an existing plugin where UUIDs change and some cleanup is needed to be done by the user to avoid duplicating existing accessories with the same name.
