Suggest use of depends_on in compose over the waiting scripts

💡 Description

Currently, the test profiles (and possibly others) use scripts which wait/sleep to ensure initialisation order.

@jordanpadams @tloubrieu-jpl possibly there's a reason for the current implementation, but if not I'd suggest letting me clean up the container dependency chain by leveraging the depends_on directive.

This would avoid unnecessary waiting when running the test profiles, in addition to being better practice.

That was considered and used sometimes but it was more complicated to implement in some cases, @ramesh-maddegoda worked on that.
Lately I was thinking I would rather deprecate the docker compose scripts in favor of a terraform apply/automated test/terraform destroy sequence which would contribute more directly to our deployment automation.
