Enforce a trailing slash (or not having one)

[angrybrad]

It would be good if users could enforce the existence (or non-existence) of a trailing slash for URLs.

There is the addTrailingSlashesToUrls config setting, but that applies at the application level and only for URLs that Craft auto-generates.

Our edge worker would need to account for this.
