Add support for per server configuration

[ghale]

you might have a single job deployed to two (or more) servers that needs a slightly different configuration on each server.

Added to v0.2.0

You can override config with a closure on the server directive:

jobs {
  myjob {
    server servers.test, {
      xml override { projectXml ->
        // do something with the xml
      }
    }
  }
}
