ci: Use testcontainers to spin up redis and datastore instances

[achals]

Signed-off-by: Achal Shah achals@gmail.com

What this PR does / why we need it:

Running integration tests for contributors has been challenging since they don't always have access to GCP or AWS. This makes development or contributions harder than they need to be.

Additionally, there's some infrastructure that's needed to run tests locally - such as redis. This shouldn't have to be installed by contributors explicitly if it's not necessary.
