Changes

Flagsmith always performs a request to the AWS Instance Metadata Service (IMDS) on startup, whether it is running on AWS or not. This was presumably used in an older infrastructure configuration which is no longer required.

How did you test this code?

Not tested - going to validate this in staging.
