AWS metadata is assumed when running in the cloud

[TobyHFerguson]

Somewhere the system attempts to grab instance metadata using the AWS metadata endpoints. This doesn't work when running on GCP :-(

This has no significant behavior on the overall demo - its nothing but a minor annoyance and an error in the logs.

The error looks like this:

2020-04-20 19:01:04.674 WARN 1 --- [ main] com.amazonaws.util.EC2MetadataUtils : Unable to retrieve the requested metadata (/latest/meta-data/instance-id).
