Adding environment to env vars added in _setEnvironmentVars().

[aemmons]

This update includes the 'environment' env variable with the deploy.env vars at the top of the handler when using --configFile flag with package or deploy command.

This allows for logic within the lambda function similar to:

if(process.env.environment === 'production'){
    // Production logic.
}else{
    // Non-production logic
}

or

var settings = {
    production: { /* Production settings */ },
    staging: { /* Staging settings */},
    dev: { /* Dev settings */ }
}
var config = settings[process.env.environment || 'dev' ];
