fix: remove sagemaker-local network before compose

[bzheng06]

Issue #, if available:
Issue #4659

Description of changes:

Simple bug fix to the linked issue, run "docker network rm sagemaker-local" before doing the docker compose during setup for a processing job in local mode, stream the output and continue if the network rm fails. The bug I was seeing was from the sagemaker-local network already existing before the job was ran, so this should tear it down before docker-compose and fix it.

Testing done:

No new tests added, ran with existing unit tests locally and results remain the same.

This also fixes the scenario when a user ctrl+c's or kill -9's the python process running a local mode job so it never cleans up the compose stack. That happens more frequently than one would think.
