Would be nice if credentials could be used within the `Options { }` block.

Currently this is not possible:

    options {
        timestamps()
        timeout(time: 15, unit: 'MINUTES')
        disableConcurrentBuilds()
        withCredentials([string(credentialsId: 'thc-wh-teams-notify', variable: "WH_URL")]) {
            office365ConnectorWebhooks([
                [name: "Office 365",
                url: ${WH_URL},
                notifyBackToNormal: false,
                notifyFailure: true,
                notifyRepeatedFailure: false,
                notifySuccess: false,
                notifyAborted: true]
            ])
        }
    }

results in:
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 14: Options definitions cannot have blocks @ line 14, column 9.
withCredentials([string(credentialsId: 'thc-wh-teams-notify', variable: "WH_URL")]) {
