[Xunop]

Describe the bug

The unittest will fail on riecv64 devices or devices with low performance.

Expected Behavior

Pass all unit tests.

Current Behavior

relevant logs:

======================================================================
FAIL: test_shutdown_complete_singleton (test_io.EventLoopGroupTest.test_shutdown_complete_singleton)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/build/python-awscrt/src/aws-crt-python/test/test_io.py", line 41, in test_shutdown_complete_singleton

AssertionError: False is not true

----------------------------------------------------------------------
Ran 292 tests in 156.700s

FAILED (failures=1, errors=1, skipped=152)

Reproduction Steps

pyver=$(python -c "import sys; print('{}{}'.format(*sys.version_info[:2]))")
export PYTHONPATH="$PWD:$PWD/build/lib.linux-$CARCH-cpython-$pyver"
python -m unittest discover test

Possible Solution

Extension of time limits:
