Full support for air gapped environments

When CI is setup in an internet-less environment, then tools or resources need to be pre-configured. For example, the cf cli is downloaded from the internet but would like to also be able to set it up as either a resource (Concourse) or a tool (Jenkins). In Jenkins I'm thinking it would be done like this using the declarative syntax:

pipeline {
    agent any
    tools {
        cf 'cf-cli-6.29.1+d5129d651.2017-08-17' 
    }
    stages {
        stage('Example') {
            steps {
                sh 'cf -v'
            }
        }
    }
}

Then, pipeline shell scripts would need to know or be told when something is preconfigured or needs to be downloaded.

As a workaround, for now, I guess you'll need to remove the curl command from the scripts. I think we could provide a switch so as not to curl anything.
