feat(python): restart with concurrency 1 if OOMed

[windmill-internal-app]

/plan sometimes on uv pip install with high concurrency subprocesses may get killed by OOM, we spawn multiple uv pip installs and I want you to detect if process was killed by OOM (Usually exist status is 137) and if so restart installation with download_concurrency_limit set to 1, big warning to terminal and logs. If it fails again - give up. Request made by @pyranota
