Build relevant test infrastructure and utilities that could let us easily write a test to do the following:

• Backwards compatibility: Spin up a mongostream container for the currently released version, obtain a checkpoint, then spin up a containuer using the PR branch to resume from the checkpoint , do some dataflow and ensure correctness
• Forwards compatibility in case we have to rollback: Create a checkpoint using the current new code that is being proposed to be merged. Spin up a mongostreams container corresponding to the currently released version. Resume from the created checkpoint, create some dataflow and ensure correctness of output
• Write tests for the configured container memory limits and making sure we never oom (but fail out via the memory tracker instead)
