CronConnectorEnvironment does not specify 'Worker' Tier

[Delphenium]

The cron jobs in the CronConnectorEnvironment do not actually run, since the environment defaults to the "WebServer" tier.

As per the documentation here: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features-managing-env-tiers.html
cron.yaml can only be used on the worker environment tier to specify cron jobs.

Updating the Cloud Formation template (CronConnectorEnvironment) to indicate the 'Worker' tier for the EB environment fixes this.

Thanks for the feed back we will look to add this bugfix to the next release.
