Jobs-api currently has routes with trailing slashes, and will treat the same route without the expected slash as a different endpoint.

With the future consolidated toolforge cli in mind, we'd like jobs-api to behave like the other toolforge apis, i.e. not require trailing slashes. For backward compatibility reasons however, we do want trailing slashes to also work.

So e.g. /v1/tool/some-tool/images and /v1/tool/some-tool/images/ should work the same.
