To remove the chance for ambiguous environment parameters, use the
full module name when evaluating environment parameters. For example:

Given two modules, nested and nested2, and they both have a
component named `deployment`, when setting environment parameters for
enviromnet `nested2` component `deployment`,
the ksonnet user will have to set the parameters like:

`ks param set nested2.deployment replicas 3`
