Can not provide custom URL as a tenant URL

[Łukasz Koniecki]

See: https://github.com/dynatrace-oss/dynatrace-gcp-function/blob/master/scripts/setup.sh

while ! [[ "${DYNATRACE_URL}" =~ ^https:\/\/[a-z0-9-]{8}\.(live|sprint|dev)\.(dynatrace|dynatracelabs)\.com\/$ ]]; do read -p "Enter Dynatrace tenant URI: " DYNATRACE_URL done

script supports only SaaS tenant URLs. It does not support custom Cluster AG URL for managed.
