CLI command to clear existing apphost cache

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

Prob part of the config feature, but I changed the name of my apphost csproj and now have to manually go into the json. Maybe we need an `aspire reset --hard` equivalent? cc @mitchdenny
