cutOutTerminatedPath cuts out the resource path terminated with the provided marker (path segment suffix). e.g. subPath: "/space1/space2/+/authToken", marker: "/+" => "/space1/space2" e.g. subPath: "/space1/space2.git", marker: ".git" => "/space1/space2" e.g. subPath: "/space1/space2.git/", marker:

(subPath string, marker string)

// case 2: xxxxxxxxxxxxxxxxxxxxxxxxM/ (M is at the end and it should have a / after it)
// case 3: xxxxxxxxxxxxxxxxxxxxxxxxxM (M is at the end).
