Define variables for the server URL

[thetutlage]

I have schema that uses the server property. Following is the snippet of the same.

  - url: http://localhost:{port}/{version}
    description: Local server
    variables:
      version:
        enum: ['v1']
        default: 'v1'
      port:
        default: '3333'

When validating the response against the schema, I want to pass the variables for port and version so that the validator can find the related paths defined in the schema.

Right now the validator fails with the error TypeError: Invalid URL.
