fix(integ): capture exit codes of parallel tests

[jericht]

Notes

Fixed the parallel integration test code to capture the exit code of each integration test and have the script finish with exit code 0 if all tests succeeded, otherwise its exit code is 1.

Testing

• To verify the exit code logic works correctly, I commented out any calls that deployed/destroyed CF stacks, and replaced the calls to component_e2e.sh to a script runCode.sh that returns a random exit code:

#!/bin/bash

sleep $((RANDOM % 3))
exit_code=$((RANDOM % 2))
exit $exit_code

The replaced code looked like:

# ( (../common/scripts/bash/component_e2e.sh "$COMPONENT_NAME"; exit_code=$?; echo $exit_code > "$INTEG_TEMP_DIR/${COMPONENT_NAME}_exitcode"; exit $exit_code) \
# || ../common/scripts/bash/component_e2e.sh "$COMPONENT_NAME" --destroy-only) &
( (~/tmp/runCode.sh; exit_code=$?; echo $exit_code > "$INTEG_TEMP_DIR/${COMPONENT_NAME}_exitcode"; exit $exit_code) \
|| echo "Failed") &

I ran the integ tests with RUN_TESTS_IN_PARALLEL=true and verified the script captured all exit codes and exited with the appropriate code.

• Ran the script as-is in parallel mode and ensured it still works as expected
